talking about possibilities:
i use [without any problem on win98] two dos programs
simultaneously reding/writeing modems on com ports.
have you checked spooler is not taking both ports?
windows sometimes modifies port setting, so dos app may not find it.
for testing [& experimenting] purposes, it would be ideal to have
two external modems connected at same time to ports, and trying to
communicate with "at " command set.
on that way you should verify port availability.
