Does it support hardware flow control on the console port? If not, then
you're going to have a problem if the machine is seding characters at,
say, 1200 (about 120 cps) baud and your tty is only taking them at 110
baud (about 10 cps, since 110 baud often implies 2 stop bits). You've
got to have a way to tell the faster side to stop sending for a bit.
What does the mod consist of? I can't believe it's really permanent
(although it might well involve soldering to undo it). Losing 38400 buad
is surely not a problem, since few, if any, classic terminals ran at that
speed, and you don't _need_ that sort of data rate for a tectual terminal
