In one of my first real PIC projects, I had wanted to interface a few 
small PICs which either had no hardware serial support or just the basic 
UART.  None of the protocols I saw seemed very simple, so I rolled my own.

I don't necessarily recommend it; it was a fun hobby project, and it 
worked fine, but it's obviously incompatible with anything else out 
there.  So I guess I'm kind of reluctantly offering to share my protocol 
and code if you (or anyone) want it, but also saying that in hindsight I 
probably should have stuck with something established.

FWIW, mine is fixed baud rate, master/slave, designed by a software 
architect who dabbles with hardware... simpler to use (for me) than 
anything else I've seen, but probably has some problems I haven't 
discovered yet.
