  This demo is based on the GD32M3203Z-EVAL board, it provides a basic communication
between USART1 and the hyperterminal. 

  After system start-up, the txbuffer is sent by USART1, the hyperterminal will receive
the data of txbuffer. Then a string end by '\r' is sent from the hyperterminal. If USART1
receives the data, it will send the received data to the hyperterminal. The hyperterminal
should open RTS and CTS function.

  JP14 must be fitted. Unplug jumper cap conneted to PA2, PA3 such as JP13 and JP20.
