* board using a protocol over TWI communication.
* @see trunk/digital/io/doc/proto_asserv.txt
* @todo
- * - protect code from sending a command when the previous one is not
- * finished yet.
- * - a consequence of previous item is that commands can failed. Maybe all
- * return values should be 'uint8_t'.
+ * - the function to send a new command to the asserv board is protected from
+ * sending one when the previous is not finished yet. But the information is
+ * not raised to the upper layer (io). It can be a bad idea to give this
+ * information to the upper layer because it can be mis-interpreted or
+ * ignored.
