Hi Paul,

38400 is the baud rate. I like the idea of using the pacing, but I am pretty sure that the SERIN / SEROUT combos are limited to 19200 max in terms of Baud Rate. 38400 is easy with a hardware UART and a 20MHz crystal.

I think I'll grab a bit of proto board and a 16F and see if I can fool around with some code to get it working.

Thanks,
Bill
