I'm trying to perform a data conversion between an old TRS-80 model II
and an IBM AT. Ideally, I'd like to impliment a serial link between the
two machines and zip the data accross the link. I'm running into problems
wiring the cable however. I tried a minimal connection of just:

rx	tx
tx	rx
gnd	gnd

But I something seems awry. I get garbage ALL the time. I.E they're talking
but not the same language. I've tried all baud rates from 300-9600 with
no sucess. Can someone give me pinouts for a Mod II to AT NULL modem cable?

Thanks!
