This sample demonstrates UART communication. When the program is executed, a string is transmitted through the serial interface, and can be seen using a serial terminal program like Hyperterminal or Minicom. The serial terminal program should be configured with the following parameters: 9600 baudrate, 8 data bits, no parity, 1 stop bit. Also note that while using a serial terminal program, the USBSIO DIP switches 3 & 4 should be in OFF position.
