Hmm, good point, I have to admit that I was thinking (with my strong C bias) that we'd be dealing exclusively with 8-bit data. I used an XOR checksum when doing data communications through 3201 poll select. Slow as molasses at 1200, it sped up a little when we went to 9600.

Update: Cool! My fiftieth writeup. How time flies.
