Several possibilities:

The modem is jumpered to use an IRQ that is already in use by your system.

Windows is using a different IRQ for the COM port that the modem is jumpered to.(I assume this is Win 3.X.)

It's a plug-and-play modem and your're not loading an ISA PNP Manager.

Any one of these will require more info about the modem to fix.Best would be the manual - hopefully your friend still has it.In lieu of that,we'll need more info:
-any names/numbers from the modem board itself,especially 'FCC ID'
-the numbers from the biggest chip on the board.
-do you see any jumpers? If so,are they labeled?

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

in dos, type in MSD, hit enter, go to the irq listing, it will show you what irq the modem is using.  then in windows, open accessories, terminal.  click settings, communications, play with the speed and the comport.  I'd sugguest 19200 & com 2 to start. then hit ok.  type in ati3, hit enter see what comes back. should tell you the details of the modem, including mfgr, speed, model # sometimes too

A jumper is a tiny plastic covered (usually black, but sometimes colored) connector between two pins on a circuit board.  They act as switches, closing the electrical circuit.  If you look on the modem, you'll probably see an area (perhaps half an inch long to maybe an inch) with pins coming up from the card.  One or more of these will probably be "jumpered" (connected with a jumper).  If you're lucky they may have writing on the card itself, often tiny, saying things like "IRQ 3" or "COM2" or something to that effect.  If you can find these and post what they say, we can better help you.

we need something more about the modem model. If it is internal then look at the mai chip on it and say what is written there

The modem will have no IRQ-jumper since it is connected to the serial port. Only the serial port can change the IRQ, and this have nothing do to with the modem. Check if all com ports are available to your system (Pug in yout mouse to your second port, and check if you can work wioth it or use msd).

rbr - you're assuming it's an external.  the vast majority of internal modems DO have jumpers.  I think most of us have assumed it was an internal modem because of the way the question was phrased.  "she gave me her modem to put in my 386."
