+This example program sends some characters on USART3 on the ST STM32-based
+Olimex STM32-H103 eval board (see http://olimex.com/dev/stm32-h103.html
+for details).
+
+The terminal settings for the receiving device/PC are 38400 8n1.
+
+The sending is done in a blocking way in the code, see the usart_irq example
+for a more elaborate USART example.
