Try my "uarttest" program: http://www.brouhaha.com/~eric/pic/uarttest.html From the description: The program "uarttest.asm" is a program to demonstrate interrupt-driven use of the hardware UART available on some of the midrange PIC16Cxx devices. It also demonstrates techniques for implementing circular buffers, command parsing, hexadecimal I/O, and text message output. Cheers, Eric
