Modem (ISA)
Jump to the self-diagnostic flowchart, or select the specific problem you're having with your modem:
MY MODEM DOES NOT APPEAR IN WINDOWS 9X DEVICE MANAGER
I'M NOT GETTING A DIALTONE FROM MY MODEM
I CAN'T CONNECT TO MY INTERNET SERVICE PROVIDER (ISP)
I'M GETTING A PORT ERROR WHEN PERFORMING A SELF-DIAGNOSTIC
HOW DO I INSTALL AN ISA PNP MODEM IN WINDOWS NT?
SELF-DIAGNOSTIC FLOWCHART
CONFIGURE MODEM FOR PLUG AND PLAY (PNP) MODE
GO INTO SYSTEM BIOS SETUP AND DISABLE COM2
MAKE SURE PnP IS ENABLED IN THE BIOS AND CHECK DEVICE MANAGER
PERFORM MODEM SELF DIAGNOSTIC TEST
1. If you have an ISA plug and play (PnP) modem, make sure it is
configured for PnP mode, not legacy mode. (Refer to your modem manual for
more instructions.)
2. Then go into the BIOS setup and make sure serial port 2 or COM2
is disabled. If you're using Windows 9x, make sure the PnP option in the
BIOS is set to enabled or yes. Set it to no or disabled if you're using
Windows NT instead.
3. For Windows 9x, start the system in normal mode and 9x should
auto-detect the modem and ask you for the drivers. Click here
for a list of PREMIO ISA PnP modems.
4. If 9x does not detect the modem, go into Device Manager
(right click on My Computer / Properties / Device Manager tab). Look under Other Devices or
Unsupported Devices and see if a modem is listed in there; if it is remove it
and restart 9x.

1. There are two phone jacks in the back of the modem: one for the phone
line, and the other for your telephone. Make sure you did not reverse the
connector on those two ports!
2. Also, connect a telephone directly to the phone line and make sure
you hear a dial tone. If you're using the modem in an office environment,
check to make sure the phone line you're using support a data call. Most offices
with a PBX (public branch exchange) system have phone lines that only support
voice calls.

1. If your modem is configured correctly and you can dial out, then mostly
likely the problem is between the modem and your ISP.
2. Call your ISP's technical support and see if they can help you
with the problem. To connect to an ISP, you'll have to manually setup
the TCP/IP protocol and the correct ISP DNS IP addresses in the Dial Up Networking
section.
3. If you are not familiar with those terms and settings, your local
ISP support rep should be able to work you through each of the necessary
settings.

1. If you have an ISA modem, it should be set to COM2. Go into your
BIOS setup and make sure COM2 or serial port B is disabled under integrated
peripherals. Also, make sure Plug and Play OS support is set to yes or enabled.
2. Next, go into Device Manager (right click on My Computer / Properties / Device Manager tab)
and double click on Modem. Your modem should be listed under this entry. Double-click
on your modem and you should see a Resources tab associated with your modem. If the
Resources tab is not present, then most likely you're loading the wrong modem
driver.
3. If the problem still persists, restart your system and go into
Safe Mode (hit F8 when Windows 9x starts) and go to Device Manager. Double click on Ports (COM & LPT) and
remove all the entries that read Communication port (COMx). Then restart your
system in Normal mode.

1. Configure your ISA modem for plug and play mode of operation. Refer
to your modem manual for instructions.
2. Go into your system BIOS setup and set plug and play OS support to
NO or DISABLED. Also, disable COM2 or serial port B from the integrated peripherals
setup menu.
3. Start Windows NT and login as the administrator; you must login as
the administrator to add or change any new hardware on a NT system.
4. Go to Control Panel / Modem and let NT autodetect the modem. It should
find your modem on COM2.
5. Finally, click on the "Have Disk" button and insert the Windows 9x modem
driver to complete the installation.

1. If you're using Windows 9x, you must configure your ISA modem
for plug and play mode of operation, before installing the modem into
your system.
2. Consult your modem user's manual on how to setup the modem
for plug and play mode.
1. It's best to configure your modem for COM2 or serial port 2.
2. To do this, go into your system board BIOS setup (hit the DELETE
key during the system memory count). Then go to Peripheral Setup or
Integrated Peripheral and look for an option that reads COM2 or serial
port 2. Set this option to DISABLED.
3. Save the BIOS setting and exit.
1. If Windows 9x fails to detect your modem at startup, then check
to make sure the Plug and Play option is set to YES or ENABLED in the system
board BIOS.
2. To do this, go into your system board BIOS setup (hit the DELETE
key during the system memory count). Then go to PCI/PnP Configuration for
Award BIOS, and set the PnP OS option to YES.
3. Save the BIOS setting and exit.
4. Additionally, go into Windows 9x Device Manager and check to make
sure the modem is not listed under Unsupported Device or Other Device. If the
modem is listed there, you must remove it and restart the system.
1. Once you have properly installed the modem driver, you can test
the modem to see if it works.
2. Go into Control Panel / Modem and click on the Diagnostic tab.
Your modem should be listed as COM2 under the Port column. Highlight it
and click on the More info... button.
3. If you get a status window then your modem is properly configured
and ready for use.
