Example description
===================
This example provides a description of how  to use the UART with hardware flow
control and communicate with the Hyperterminal.
First, the UART0 sends the TxBuffer to the hyperterminal and still waiting for
a string from the hyperterminal that you must enter which must end by '\r'
character (keypad ENTER button). Each byte received is retransmitted to the
Hyperterminal. 
The string that you have entered is stored in the RxBuffer array. The receive
buffer have a RxBufferSize bytes as maximum.

The UART0 is configured as follow:
  - Word Length = 7 Bits
  - Two Stop Bit
  - No parity
  - BaudRate = 115200 baud
  - Hardware flow control disabled
  - Receive and transmit enabled
  - Receive and transmit FIFOs are enabled
  - Transmit and Receive FIFOs levels have 8 bytes depth

91x_conf.h  Library Configuration file
91x_it.c    Interrupt handlers
main.c      Main program


Hardware environment
====================
 - All the UART0 signals (Rx, Tx) must be connected to a DB9 
   connector using a RS232 transceiver.
   + UART0_Rx (P5.1)
   + UART0_Tx (P3.4)

 - Connect a null-modem female/female RS232 cable between the DB9 connector 
   and PC serial port.  

 - Hyperterminal configuration:
    - Word Length = 7 Bits
    - Two Stop Bit
    - No parity
    - BaudRate = 115200 baud
    - flow control: None
  
  
How to use it
=============
In order to make the program work, you must do the following :

- Put the Jumpers U0TX to  on the position 1-3(only for STR912-SK IAR Board)
- Run the example
