   7          // Program Description:
   8          //
   9          // This program demonstrates how to configure the C8051F020 to write to and read
  10          // from the UART interface. The program reads a word using the UART1 interrupts
  11          // and outputs that word to the screen, with all characters in uppercase
  12          //
  13          // How To Test:
  14          //
  15          // 1) Download code to a 'F02x device that is connected to a UART transceiver
  16          // 2) Verify jumpers J6 and J9 are populated on the 'F02x TB.
  17          // 3) Connect serial cable from the transceiver to a PC
  18          // 4) On the PC, open HyperTerminal (or any other terminal program) and connect
  19          //    to the COM port at <BAUDRATE> and 8-N-1
  20          // 5) Download and execute code on an 'F02x target board.
