I was having the same problem with a Zenith 248 that came with a funky 
adaptor that plugged into one of the bigger ports on back and had two ports
on the other side of it - I forget the specifics, but the effect was that
with the adaptor, the modem could not be plugged into COM1 but only COM2
which was on the back of the adaptor.

Anyway, I tried the DOS assign command and I believe that command is only
useful for assigning a COM port to an LPT port and possibly vice versa.  It
did not work assigning one COM port to another COM port.

I ended up yanking the stupid adaptor off of there.
