Fiddling with a Nano 1.2.1 port

Hi all,

FYI, I am fiddling with a Nano 1.2.1 port to DJGPP 2.04a.
I've added some code for SFN-safe operation. No speller
though -- Nano uses a forking model for that so a major
rewrite of that section will be needed. Compiles nicely.
Currently going through a test checklist, so if there are
no major glitches I'll upload it somewhere in a few days.

1. Fiddling with ports

I have a program that wants my modem on either com1 or com2.  Unfortunately
I have a serial card in both and my modem is internal.  I don't have
any docs on disabling com1 or com2 and I'm pretty sure I can't reassign
them to another com port on the serial card because "com2" is actually
written on the board (the board is something like an sst-xxxx so if you
know how to do this let me know).

My question there a way to fool my program into using com4
(some DOS trick, fiddling with addresses or something)?

Any suggestions appreciated.  Please respond by e-mail.
