+
+1. Introduction
+---------------
+
+USPP Library is a multi-platform Python module to access serial ports. At the
+moment, it only works in Windows, Linux and MacOS but as it is written entirely
+in Python (doesn't wrap any C/C++ library) I hope you can extend it to support
+any other platforms.
+
+
+2. Motivation
+-------------
+
+I like very much to make electronic widgets with microcontrollers, specially
+those that can be connected to the computer to send and receive data.
+Some months ago, I discovered Python and inmediatelly liked it a lot.
+I started playing with it and saw that I could use it to make prototypes of
+comunication protocols between computer and microcontrollers really
+fast and easily than using C. At the same time, I was interested in
+working over different platforms.
+I started looking for Python modules to access serial port and I found
+the following projects:
+
+ * win32comport_demo from the win32 extension module
+ * win32comm module of wheineman@uconect.net
+ * Sio Module of Roger Rurnham (rburnham@cri-inc.com)
+ * pyxal (Python X10 Abstraction Layer) of Les Smithson
+ (lsmithson@open-networks.co.uk)
+
+but they were not multi-platform, were just a wrap of propietary libraries or
+were just simple examples of serial port access.
+For these reasons and also for learning more Python, I decided to start
+this project. Of course, I have used all this projects as reference to
+my module and so, I want to thanks the authors for their excellent work and
+for allowing us to study the code.
+I hope you enjoy using the uspp module as much as I am enjoying doing it.
+
+
+3. Where can I find it
+----------------------
+
+You may find it at:
+ * http://ibarona.googlepages.com/uspp
+ * http://www.telefonica.net/web/babur
+
+as a tar.gz package or as a winzip file.
+
+
+4. Features
+-----------
+
+This module has the following features:
+
+ - hight level access to serial port under several platforms.
+ - autodetects the platform in which it is working and exports
+ the correct classes for that platform.
+ - object oriented approach.
+ - file object semantic operations over the ports.
+ - allows using the serial port with different speeds and
+ characteristics.
+ - RS-232 and RS-485 modes (now only RS-232). In RS-485 mode
+ the communication is half-duplex and uses the RTS line
+ to control the direction of the transference.
+ - blocking, non-blocking or configurable timeout reads.
+
+
+5. Prerequisites
+----------------
+
+You need the following to use the library:
+
+ - Python 2.1 or better
+ - In windows you need the win32 extension modules
+
+
+6. Usage and documentation
+--------------------------
+
+You only have to import in your program the uspp module and automatically
+it loads the correct classes for the platform in which you are running
+the program.
+
+First of all you have to create a SerialPort object with the settings you
+want. If a SerialPortException is not generated then you just can
+use the read and write methods of the object to read and write to
+the serial port.
+
+Example:
+
+>>> from uspp import *
+>>> tty=SerialPort("COM2", 1000, 9600)
+>>> # Opens COM2 at 9600 bps and with a read timeout of 1 second.
+>>> tty.write("a") # Writes a character to the COM2 port
+>>> # Now suppose we receive the string "abc"
+>>> tty.inWaiting()
+3
+>>> tty.read()
+'a'
+>>> tty.inWaiting()
+2
+>>> tty.read(2)
+'bc'
+
+
+Documentation of the different classes and methods can be found on
+uspp module docstring.
+
+
+7. Where does it work
+---------------------
+
+The library has been tested in Windows 95, Windows XP and Windows 2000
+machines with Python 2.1+ and in a Linux (2.0.34 kernel) machine with
+Python 2.1+.
+
+
+8. Known problems
+-----------------
+
+
+
+
+9. To-do list
+-------------
+
+This is the to-do list:
+
+ - implement RS-485 mode.
+ - port the library to other platforms so that it can be really
+ multi-platform.
+
+
+10. Porting to other platforms
+-----------------------------
+
+If you want to port the library to other platforms you only have to follow
+these steps:
+
+* Create a new python file called SerialPort_XXXX.py in which you
+implement the same public classes and methods found in the SerialPort_win
+and SerialPort_linux modules.
+* Append the new platform to the uspp.py file.
+
+
+11. Licence
+----------
+
+This code is released under the "LGPL" that can be found in
+http://www.gnu.org/copyleft/lesser.html or in the lesser.txt file that
+is with the library.
+If you use this software, I'd like to know about it.

+
+1. Introducción
+---------------
+
+La librería USPP es un módulo desarrollado en Python para el acceso
+multiplataforma al puerto serie. En el momento, sólo funciona en Linux
+Windows y MacOS, pero como está escrita completamente en Python
+(no es únicamente un recubrimiento en Python de una librería desarrollada
+en C/C++) espero que pueda ser ampliada para que soporte otras plataformas.
+
+
+2. Motivación
+-------------
+
+A mí me gusta mucho hacer pequeños cacharros electrónicos con
+microcontroladores, especialmente aquellos que pueden ser conectados a
+un ordenador para enviar y recibir datos.
+Hace un par de meses descubrí Python y realmente me encantó.
+Empezé a jugar con él y ví que podía utilizarlo para hacer prototipos
+de protocolos de comunicación entre el ordenador y los microcontroladores
+de manera mucho más fácil y rápida que utilizando C (que era el lenguaje
+que solía utilizar). Al mismo tiempo, estaba interesado en poder utilizar
+los desarrollos bajo diferentes arquitecturas.
+Empezé a buscar en la red módulos de Python que accedieran al puerto serie
+y encontré los siguientes:
+
+ * win32comport_demo que viene junto a la extensión win32.
+ * Módulo win32comm de wheineman@uconect.net.
+ * Sio Module de Roger Rurnham (rburnham@cri-inc.com)
+ * pyxal (Python X10 Abstraction Layer) de Les Smithson
+ (lsmithson@open-networks.co.uk)
+
+pero no eran multiplataforma, eran únicamente un recubrimiento de una librería
+propietaria o eran simples ejemplos de acceso al puerto serie bajo una
+determinada plataforma.
+Por estas razones, y también por supuesto, por aprender más Python, decidí
+empezar este proyecto. Por supuesto, he utilizado los módulos indicados
+anteriormente como referencia para realizar mi librería y por tanto, me
+creo en la obligación de felicitar a sus autores por su excelente trabajo y
+por haberlo compartido con los demás.
+
+Espero que disfrutes utilizándo el módulo uspp tanto como yo lo
+he hecho haciéndolo.
+
+
+3. Dónde encontrar la librería
+------------------------------
+
+Puedes encontrarla en:
+ * http://ibarona.googlepages.com/uspp
+ * http://www.telefonica.net/web/babur
+
+como un fichero tar.gz o como un fichero .zip.
+
+
+4. Características
+------------------
+
+Este módulo tiene las siguientes características destacadas:
+
+ - acceso de alto nivel al puerto serie bajo diversas plataformas.
+ - autodetecta la plataforma en la que se está ejecutando y
+ carga las clases adecuadas para esa plataforma.
+ - Orientado a objetos.
+ - Las operaciones sobre el puerto serie tienen la misma semántica
+ que las operaciones sobre objetos de tipo fichero.
+ - permite utilizar el puerto serie con diferentes velocidades y
+ características.
+ - permite la utilización del puerto bajo dos modos de funcionamiento:
+ RS-232 y RS-485 (de momento, sólo RS-232). En modo 485 la
+ comunicación es half-duplex y se utiliza la línea RTS para controlar
+ la dirección de la transferencia.
+ - lecturas en modo bloqueante, no bloqueante o con timeout.
+
+
+5. Pre-requisitos
+----------------
+
+Se necesita los siguiente para utilizar la librería:
+
+ - Python 2.1 o superior
+ - En windows los módulos win32
+
+
+6. Utilización y documentación
+------------------------------
+
+Únicamente tienes que importar en tu programa el módulo uspp y automáticamente
+él se encarga de cargar las clases adecuadas para la plataforma en la que
+se está ejecutando el programa.
+
+Lo primero de todo, tendrás que crear un objeto de tipo SerialPort con las
+características que desees. Si no se genera ninguna excepción del tipo
+SerialPortException, puedes utilizar los métodos de lectura y escritura
+del objeto para leer y escribir en el puerto serie.
+
+Ejemplo:
+
+>>> from uspp import *
+>>> tty=SerialPort("COM2", 1000, 9600)
+>>> # Abre el puerto serie COM2 a 9600 bps y con un timeout de 1 segundo.
+>>> tty.write("a") # Envía el carácter 'a' al puerto serie.
+>>> # Ahora suponemos que recibimos el string 'abc'
+>>> tty.inWaiting()
+3
+>>> tty.read()
+'a'
+>>> tty.inWaiting()
+2
+>>> tty.read(2)
+'bc'
+
+
+La documentación de las diferentes clases y métodos que componen el módulo
+puede encontrarse en el string de documentación del módulo uspp.
+
+
+7. Dónde funciona
+-----------------
+
+La librería ha sido probada en una máquina con Windows 95, Windows XP y
+Windows 2000 con Python 2.1+ y en un Linux (con el kernel 2.0.34) con Python
+2.1+.
+
+
+8. Problemas pendientes
+-----------------------
+
+
+
+
+9. Tareas pendientes
+--------------------
+
+Esta es la lista de tareas pendientes:
+
+ - implementar el modo RS-485.
+ - portar la librería a otras plataformas de forma que sea
+ realmente multiplataforma.
+
+
+10. Portado a otras plataformas
+-------------------------------
+
+Si quieres portar la librería a otras plataformas sólo tienes que seguir
+los siguientes pasos:
+
+* Crear un nuevo fichero en python llamado SerialPort_XXX.py en el que
+implementes las mismas clases y métodos públicos que aparecen en los
+módulos SerialPort_win y SerialPort_linux.
+* Añadir la nueva plataforma en el fichero uspp.py.
+
+
+11. Licencia
+------------
+
+Este código se libera bajo la licencia "LGPL" que puedes encontrar en
+http://www.gnu.org/copyleft/lesser.html o en el fichero lesser.txt que
+acompaña a la librería.
+Si utilizas este software estaría muy agradecido de saberlo.

+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+

+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU

+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+ <div class="content-item"><div id="g_body"><h2>Introduction</h2><p><i>USPP Library </i>is a multi-platform Python module to access serial ports.
+At the moment, it only works in Windows, Linux and MacOS but as it is written entirely in Python (doesn't wrap any C/C++
+library) I hope you can extend it to support any other platforms.&nbsp;</p><h2>Motivation</h2><p>
+I like very much to make electronic widgets with microcontrollers, specially
+those that can be connected to the computer to send and receive data.
+</p><p>Some months ago, I discovered Python and inmediatelly liked it a lot.
+I started playing with it and saw that I could use it to make prototypes of
+comunication protocols between computer and microcontrollers really
+fast and easily than using C. At the same time, I was interested in
+working over different platforms.
+</p><p>I started looking for Python modules to access serial port and I found
+the following projects:
+</p><ul><li><i>win32comport_demo</i> from the win32 extension module</li><li><i>win32comm</i> module of wheineman@uconect.net</li><li><i>Sio Module </i>of Roger Rurnham (rburnham@cri-inc.com)</li><li><i>pyxal (Python X10 Abstraction Layer) </i>of Les Smithson (lsmithson@open-networks.co.uk)</li></ul><p>but they were not multi-platform, were just a wrap of propietary libraries or
+were just simple examples of serial port access.
+</p><p>For these reasons and also for learning more Python, I decided to start
+this project. Of course, I have used all this projects as reference to
+my module and so, I want to thanks the authors for their excellent work and
+for allowing us to study the code.
+I hope you enjoy using the uspp module as much as I am enjoying doing it.</p><h2>Features</h2><p>
+This module has the following features:
+</p><ul><li>hight level access to serial port under several platforms.</li><li>autodetects the platform in which it is working and exports the correct
+classes for that platform.</li><li>object oriented approach.</li><li>file object semantic operations over the ports.</li><li>allows using the serial port with different speeds and
+characteristics.</li><li>RS-232 and RS-485 modes (now only RS-232). In RS-485 mode the communication
+is half-duplex and uses the RTS line to control the direction of the
+transference.</li><li>blocking, non-blocking or configurable timeout reads.</li></ul><h2>&nbsp;Prerequisites</h2><p>You need the following to use the library:
+</p><ul><li>Python 2.1 or better</li><li>In windows you need the win32 extension modules. You can get it from <a href="http://sourceforge.net/projects/pywin32/">here</a>.<br></li></ul><h2>Usage and documentation</h2><p>You only have to import in your program the <i>uspp</i> module and automatically
+it loads the correct classes for the platform in which you are running
+the program.
+
+</p><p>First of all you have to create a <i>SerialPort</i> object with the settings you
+want. If a <i>SerialPortException</i> is not generated then you just can
+use the read and write methods of the object to read and write to
+the serial port.
+
+</p><p>Example:
+
+</p><pre><tt><br>&gt;&gt;&gt; from uspp import *<br>&gt;&gt;&gt; tty=SerialPort("COM2", 1000, 9600) <br>&gt;&gt;&gt; # Opens COM2 at 9600 bps and with a read timeout of 1 second.<br>&gt;&gt;&gt; tty.write("a") # Writes a character to the COM2 port<br>&gt;&gt;&gt; # Now suppose we receive the string "abc"<br>&gt;&gt;&gt; tty.inWaiting()<br>3<br>&gt;&gt;&gt; tty.read()<br>'a'<br>&gt;&gt;&gt; tty.inWaiting()<br>2<br>&gt;&gt;&gt; tty.read(2)<br>'bc'<br></tt></pre>
+
+<p>Documentation of the different classes and methods can be found on
+uspp module docstring.</p><h2>Where does it works?&nbsp;</h2><p>&nbsp;
+The library has been tested in&nbsp; Windows 95, Windows XP and Windows 2000&nbsp; machines with Python 2.0+
+and in a Linux (2.0.34 and 2.4.20 kernels) machine with Python 2.1+.</p><h2>Porting to other frameworks</h2><p>
+If you want to port the library to other platforms you only have to follow
+these steps:
+</p><ul><li>Create a new python file called <i>SerialPort_XXXX.py </i>in which you
+implement the same public classes and methods found in the
+<i>SerialPort_win</i>
+and <i>SerialPort_linux</i> modules.</li><li>Append the new platform to the <i>uspp.py</i> file.</li></ul><h2>License&nbsp;</h2><p>&nbsp;
+This code is released under the "GPL" that can be found in
+<a href="http://www.gnu.org/copyleft/gpl.html%20">http://www.gnu.org/copyleft/gpl.html </a>or in the GPL.txt file that
+is with the library.
+</p><p>If you use this software, I'd like to know about it.</p><h2>&nbsp;Author</h2><p>

+USPP - Universal Serial Port Python Library
+
+This module exports a SerialPort class to access serial ports in
+different platforms (currently W9X and Linux) with the same code.
+
+When the library user import the uspp module, it automatically
+loads the correct class implementation for the platform in which
+is running.
+
+The public classes, exceptions and methods are the following:
+
+SerialPortException
+===================
+Exception raised in the SerialPort methods.
+
+
+SerialPort
+==========
+Class that encapsulate methods to access serial ports. It has the
+following public methods:
+
+* __init__(self, dev, timeout=None, speed=None, mode='232', params=None)
+
+ Create an object to access serial port 'dev'
+
+ Arguments:
+
+ dev: String that indicate the name of the port. Possible values are:
+ In Linux: '/dev/ttyS0', '/dev/ttyS1', ..., '/dev/ttySX' or
+ '/dev/cua0', '/dev/cua1', ..., '/dev/cuaX'
+ In W9X: 'COM1', 'COM2', ..., 'COMX'
+
+ timeout: specifies in milliseconds the inter-byte timeout. Possible
+ values are:
+ * None: For blocking readings. Time-outs are not used for reading
+ operations.
+ * 0: For non-blocking readings. The reading operation is to return
+ inmediately with the characters that have already been received,
+ even if no characters have been received.
+ * >0: For time-out readings. A character must be read in less than
+ this value.
+
+ speed: integer that specifies the input and output baud rate to
+ use. Possible values are: 110, 300, 600, 1200, 2400, 4800, 9600,
+ 19200, 38400, 57600 and 115200.
+ If None a default speed of 9600 bps is selected.
+
+ mode: string that specifies RS-232 or RS-485 mode. The RS-485 mode
+ is half duplex and use the RTS signal to indicate the
+ direction of the communication (transmit or recive).
+ Posible values are: '232' or '485'. Default to RS232 mode (the
+ only implemented just now).
+
+ params: list that specifies properties of the serial communication.
+ If params=None it uses default values for the number of bits
+ per byte (8), the parity (NOPARITY) and the number of stop bits (1)
+ else:
+ * In W9X: params must be a list with three items setting up the
+ these values in this order.
+ * In Linux: params must is the termios package mode array to use
+ for initialization.
+
+
+
+* __del__(self):
+
+ Destroy the SerialPort object and close the serial port. It is a good
+ idea that when you finish working with the serial port you explicity
+ do: del tty (where tty is a SerialPort object).
+
+* fileno(self):
+
+ Returns the file descriptor of the serial port. This information is
+ sometimes necessary for example if you want to use the select function.
+
+* read(self, num=1):
+
+ Read num bytes from the serial port. Depending the timeout value used in
+ the inicialitation this operation can be:
+
+ - Blocking (if timeout=None): The operation blocks until num bytes
+ arrive the serial port.
+ - Non-blocking (if timeout=0): The operation returns inmediatelly
+ with as many as num bytes that were waiting in the serial port to be read.
+ - Time-out (if timeout>0): A byte must arrive in less milliseconds than
+ the specified. If the number of read bytes is less than num a
+ SerialPortException is raised because a time-out has happened.
+
+* write(self, s):
+
+ Write the string s to the serial port.
+
+* inWaiting(self):
+
+ Returns the number of bytes waiting to be read.
+
+
+* flush(self):
+
+ Discards all characters from the output or input buffer.
+
+
+
+NOTE ON CHARACTERS AND BYTES
+============================
+
+The write and read methods of the SerialPort class expect data
+in string buffers. Do not think this library only works for
+ASCII communications. To interpret string elements as bytes (integer number)
+you only have to use the built-in ord() function. To convert a byte
+into a string element, use chr().
+
+Example: Suppose you want to transmit the following three bytes:
+0x02, 0x10, 0x30. You only have to do:
+
+packet = ''
+packet = packet + chr(0x02) + chr(0x10) + chr(0x30)
+tty.write(packet)
+
+So, you can see the bytes you send or receive as integers or as characters
+depending the situation.

+librería USPP es un módulo desarrollado en Python para el acceso
+multiplataforma al puerto serie. En el momento, sólo funciona en Linux,
+Windows y MacOS, pero como está escrita completamente en Python&nbsp;
+(no es únicamente un recubrimiento en Python de una librería
+desarrollada&nbsp; en C/C++) espero que pueda ser ampliada para que
+soporte otras plataformas.<i><br><br></i></p><h2>Motivacion</h2><p>&nbsp;A
+mí me gusta mucho hacer pequeños cacharros electrónicos con
+microcontroladores, especialmente aquellos que pueden ser conectados a
+un ordenador para enviar y recibir datos. Hace un par de meses descubrí
+Python y realmente me encantó. Empezé a jugar con él y ví que podía
+utilizarlo para hacer prototipos de protocolos de comunicación entre el
+ordenador y los microcontroladores&nbsp; de manera mucho más fácil y
+rápida que utilizando C (que era el lenguaje que solía utilizar). Al
+mismo tiempo, estaba interesado en poder utilizar los desarrollos bajo
+diferentes arquitecturas. Empezé a buscar en la red módulos de Python
+que accedieran al puerto serie<br>y encontré los siguientes:<br><br>&nbsp;&nbsp; &nbsp;* win32comport_demo que viene junto a la extensión win32.<br>&nbsp;&nbsp; &nbsp;* Módulo win32comm de wheineman@uconect.net.<br>&nbsp;&nbsp; &nbsp;* Sio Module de Roger Rurnham (rburnham@cri-inc.com)<br>&nbsp;&nbsp; &nbsp;* pyxal (Python X10 Abstraction Layer) de Les Smithson <br>&nbsp;&nbsp; &nbsp;&nbsp; (lsmithson@open-networks.co.uk)<br><br>pero
+no eran multiplataforma, eran únicamente un recubrimiento de una
+librería propietaria o eran simples ejemplos de acceso al puerto serie
+bajo una&nbsp; determinada plataforma.<br>Por estas razones, y también
+por supuesto, por aprender más Python, decidí empezar este proyecto.
+Por supuesto, he utilizado los módulos indicados anteriormente como
+referencia para realizar mi librería y por tanto, me creo en la
+obligación de felicitar a sus autores por su excelente trabajo y por
+haberlo compartido con los demás.<br><br>Espero que disfrutes utilizándo el módulo uspp tanto como yo lo&nbsp; he hecho haciéndolo.</p><h2>Características&nbsp;</h2><p>Este módulo tiene las siguientes características destacadas:<br>&nbsp;</p><ul><li>&nbsp;acceso de alto nivel al puerto serie bajo diversas plataformas.</li><li>autodetecta la plataforma en la que se está ejecutando y carga las clases adecuadas para esa plataforma.</li><li>Orientado a objetos.</li><li>Las operaciones sobre el puerto serie tienen la misma semántica que las operaciones sobre objetos de tipo fichero.</li><li>&nbsp;permite utilizar el puerto serie con diferentes velocidades y características.</li><li>permite
+la utilización del puerto bajo dos modos de funcionamiento: RS-232 y
+RS-485 (de momento, sólo RS-232). En modo 485 la comunicación es
+half-duplex y se utiliza la línea RTS para controlar la dirección de la
+transferencia.</li><li>lecturas en modo bloqueante, no bloqueante o con timeout.</li></ul><h2>Prerequisitos</h2><p>Se necesita los siguiente para utilizar la librería:</p><ul><li>Python 2.1 o superior</li><li>En windows los módulos win32</li></ul><h2>Utilización y documentación<br></h2><p>Únicamente
+tienes que importar en tu programa el módulo uspp y automáticamente él
+se encarga de cargar las clases adecuadas para la plataforma en la que
+se está ejecutando el programa.<br><br>Lo primero de todo, tendrás que
+crear un objeto de tipo SerialPort con las características que desees.
+Si no se genera ninguna excepción del tipo SerialPortException, puedes
+utilizar los métodos de lectura y escritura<br>del objeto para leer y escribir en el puerto serie.<br><br>Ejemplo:</p><pre><tt><tt>&gt;&gt;&gt; from uspp import *<br>&gt;&gt;&gt; tty=SerialPort("COM2", 1000, 9600) <br>&gt;&gt;&gt; # Opens COM2 at 9600 bps and with a read timeout of 1 second.<br>&gt;&gt;&gt; tty.write("a") # Writes a character to the COM2 port<br>&gt;&gt;&gt; # Now suppose we receive the string "abc"<br>&gt;&gt;&gt; tty.inWaiting()<br>3<br>&gt;&gt;&gt; tty.read()<br>'a'<br>&gt;&gt;&gt; tty.inWaiting()<br>2<br>&gt;&gt;&gt; tty.read(2)<br>'bc'</tt></tt></pre><pre><tt><tt>&nbsp;</tt></tt></pre><pre><br></pre><p><font face="arial,sans-serif" size="2">La
+documentación de las diferentes clases y métodos que componen el módulo
+puede encontrarse en el string de documentación del módulo uspp.</font></p><h2>Donde funciona<br></h2><p>La
+librería ha sido probada en una máquina con Windows 95, Windows XP y
+Windows 2000 con Python 2.1+ y en un Linux (con el kernel 2.0.34) con
+Python 2.1+.</p><h2>Portado a otras plataformas<br></h2><p></p><p>&nbsp;Si quieres portar la librería a otras plataformas sólo tienes que seguir los siguientes pasos:</p><ul><li>Crear
+un nuevo fichero en python llamado SerialPort_XXX.py en el que
+implementes las mismas clases y métodos públicos que aparecen en los
+módulos SerialPort_win y SerialPort_linux.</li><li>Añadir la nueva plataforma en el fichero uspp.py.<br></li></ul><h2>&nbsp;Licencia&nbsp;</h2><p>Este
+código se libera bajo la licencia "LGPL" que puedes encontrar en&nbsp;
+http://www.gnu.org/copyleft/lesser.html o en el fichero lesser.txt que
+acompaña a la librería. Si utilizas este software estaría muy
+agradecido de saberlo.&nbsp;</p><h2>Autor</h2><p>Esta librería ha sido creada por Isaac Barona Martínez &lt;ibarona@gmail.com&gt;.</p><h2>Versiones</h2><h3>Versión 1.0 - 24/02/2006&nbsp;</h3><p>Mucho
+tiempo después de la versión 0.1 he tenido el tiempo suficiente de
+liberar la versión definitiva de la librería. Esta versión corrige los
+errores encontrados en la versión anterior, funciona en MacOS y ha sido
+ampliada.</p><p>La libería contiene más funciones en las versiones para Linux y MacOS que para Windows.&nbsp;</p><p>Tengo que agradecer a muchas personas su contribución a esta librería, especialmente a:</p><ul><li>Damien Geranton &lt;dgeranton at voila.fr&gt;&nbsp;</li><li>Douglas Jones &lt;dfj23 at drexel.edu&gt;</li><li>J.Grauheding &lt;juergen.grauheding at a-city.de&gt;</li></ul><p>Puedes descargar los ficheros desde aqui:</p><ul><li>Zip file: uspp-0_1.zip</li><li>tar.gz file: uspp-0_1.tar.gz</li></ul><h3>&nbsp;Version 0.1 - 01/09/2001 (Septiembre 2001)</h3><p>&nbsp;</p><p>&nbsp;</p></div></div>
