good, external non-winmodem?

Hey all, I built a system for a buddys security system. the software on the
system is proprietary and basically its used to take continuous snapshots
from the 15 cameras or so all around his liquor store. The modem that came
with the system has a problem, apparantly. He cant dial into the software
from home, as he used to be able to. He just gets busy signal, but the line
is a dedicated dial-up line with no other devices on it. I actually put
winME on a p4p800-e system as the software isnt designed to run on 2k or XP.
So, the modem (which is proprietary also, it has their logo on it) is
connected to com2 via serial, and when the program is running (telxpert, its
called) the modem seems "busy" all the time. I open hyperterminal and try to
run some AT commands to hang it up and get errors. Go into control panel,
use the modem diagnostics to query the modem, and get "port already open".

Turn the program off, I can dial with the modem no prob...no more "port
already open" problems. So the software seems to be causing the prob, but I
would like to get another modem and see if the prob goes away. Are external
modems considered "non-winmodem"? hardware modems? I know the p4p800-e has
no ISA slots, only pci, so If I used an internal, it would probably be
winmodem yes? any thoughts?

I googled the "port already open" problem and tried every single thing I
could find from MS knowledge base...I'm stumped....sorry if this is OT...
