    Dwayne:

    Actually, I can't really take credit for anything but the use of
    a "GOTO $+1" as a two-cycle NOP.  As I recall, Mike Harrison's
    original code used "MOVF PC", instead... Not real safe.

    Have you actually TESTED the 19200 and 38400 baud versions?
    Maybe I'm missing something, but it looks to me as though all
    bits after the start bit will be sent at 9600 baud.
