That's odd. I had thought that all these machines used the same
serial hardware. Perhaps someone more knowledgeable than myself will
chime in.
My thoughts are that maybe you have the pc serial driver in your
kernel and not the mac (SCC?) driver. That would definitely not work.
Anyway, I'm pretty sure that setserial *doesn't* work on mac68k, so
don't bother with it. Also, in minicom, make sure you have hardware
flow control *off* as the RS-422 cable that macs use don't have flow
control lines. Also, don't try to use speeds higher than 38400.
Anyway, I'm reaching the limit of my experience, here. Anyone?
Good luck,
cbb
