I'm looking for info on implementing a parallel to serial conversion with a
PIC.  It needs to go along up to about 100m of twisted pair, so I'm
planning to use RS-422 or 485 (bidirectional link on one pair would be
ideal), with basically a standard PC parallel port at the other end.

(If anyone is interested, the idea is to connect a PC on the surface to a
Texas Instruments DSK up to 100m underwater for some underwater acoustic
comms trials)

Has anyone implemented something like this on a PIC?  Using the UART even?
I'm up to speed on PICs but haven't needed to do serial comms before on them.

TIA,
Nigel
