Yep. Thats the exact same PowerBook that I have, even down to the speed. I
never could get it to talk to the IR Tower. The same IR Tower would talk to the
older SE/30 with no problems. It may be a volage problem, or it may have
something to do with 'floating ground' state of the PB. Keep in mind that the
serial port on all Macs is RS-422, not RS-232. Connecting it to an RS-232 device
is a bit of a hack. I believe that RS-422 is a differential voltage standard,
while RS-232 is a single-ended standard.
My only suggestion would be to look into an external serial port on a PC card.
It *might* solve your problem.
