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?

All external modems are non-winmodems.

Not true, There are/or were some USB modems that were WinModems.
Every modem I've seen that attatches to a RS-232 serial port has been a
controller modem.


I know the p4p800-e has
no ISA slots, only pci, so If I used an internal, it would probably be
winmodem yes?

Not necessarily, you can easily find non-winmodems that are PCI.

This is true. U.S Robotics, Zoom/Hayes makes some.



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...


I don't think you'll be able to use the modem that the software is
using for anything else. It sound like they open the port and keep it
open. Unlikely to be related to the modem.

I suggest you install a 2nd modem - either external or internal.
Connect it to the same phone line, and see if the the two modems will
coexist on the same phone line. I suspect they will, unless (until)
the security software decides it has to dial out at the same time that
you are connected (dialed in).

This may not work if the security software is set up to answer the
phone line. Then it will answer your call as well as whatever terminal
software you have running on the 2nd modem. In that case, you'll need
another line.

You can certainly get non-winmodems that are PCI

Yes.



I've seen this problem occur when there is an IRQ argument. If there is a
serial port 2 or B on the motherboard, set it to disabled. Most WinModems
I've seen like to be set at Comm 2 IRQ 5 in the Windows settings. You may
have to remove the modem from the Windows Manager then shut down, turn on,
and let Windows rediscover the modem. Do this after you set the bios serial
2 port to disabled.

There could be another program keeping the modem off hook also. Check for a
fax program or some program that phones home to do this. Windows Update,
Anti-virus update programs, etc.
