4800 baud is the maximum I could get out of kermit and actually have it
work reliably.  Although I didn't use the best shielded cables and could
definately say that it wasn't a noise problem, it looked like the overhead
of using the FIRQ line (massaging the rest of the registers on the stack and
making OS-9 think that it was really an IRQ) kept it from going faster on
input.  Output to 19200 baud has been no problem, however.
