Barry, I snarfed the following information some time ago about using
other comports with windows. I haven't tried it, so hope this helps!

Yep.  Microsoft had to guess where COM3 and COM4 are since there is
no standard.  They made a lousy guess.  But they provide a way for
you to correct their mistake.

In SYSTEM.INI in the [386Enh] section, add

	Com3Base=03E8h

(or whatever address your modem uses, see its documentation).
For more information see the SYSINIn.TXT files.
