I'm using a Mac at home but when we had to go from OpenStep to NT at work, I
brought the PC serial cable that came with my 2100. I successfully connected
many times to 2 different computers running NT 4. I've never had to set any bit
parity, or odd things like that. I'm even running at 57600 with the help of a
nice little package on the Newt and some Windows registry tweaking. I would
suspect your cable is not good, much like it seems you suspect.
