OPTION 5
If you have both "03F8" and "02F8" and you do have another device using IRQ5 while you
don't have any external device connected to COM2 "02F8", have COM2 "02F8" IRQ3 on
your I/O card disabled. Set your modem to COM2 IRQ3 after COM2 IRQ3 has been
disabled on your I/O card.
OPTION 6
(depends on your system's multi-I/O card)
If you have both "03F8" and "02F8" and do have another device using IRQ5 while there is
an external device connected to COM2 "02F8" and a serial mouse is connected to COM1
"03F8," you can try to put your modem on COM4 IRQ3. However, this is not always
guaranteed to work. It is our experience that whether or not this kind of setting works or
not depends a lot on the multi-I/O card itself. Sometimes the I/O card does not like to
share IRQ (IRQ3 in this case) with another device. Sometimes this setting will work for
a while and suddenly stopped working. Sometimes it will work flawlessly. The PC
Bus architecture was not designed to share IRQ's.
OPTION 7
If you have a setting that matches Option 6 above and Option 6 does not work on your
system, you can try to move the device that's using IRQ5 to an unused IRQ and set your
modem to COM3 IRQ5. If the device that's using IRQ5 does not support other IRQ's,
you have ran out of available IRQ. Consult your local dealer or a consultant to see if
they can give you some advice. You must also realize that if your system is fully loaded
with no available COM Port or IRQ, another device must be sacrificed (disabled) to make
room for the fax modem.
When you find the COM Port and IRQ setting for your modem, set the modem according
to the instructions in your Fax Modem User's manual. Turn your computer off, unplug
the power cord, remove the cover to your computer, locate an available expansion slot on
the motherboard, remove the screw that's holding the slot cover if there is one, and
carefully slide the modem into the slot completely. Secure the modem in the slot with
the screw. Connect your DEDICATED phone wire to the fax/modem's "LINE" jack.
You may want to install the software that came with the package and test the modem
before you put the computer cover back. But be careful not to touch any system
components with the power cord plugged into the wall socket.

If you are skipping COM3, and you are installing any Windows based communications
software, you will need to add the following two lines to your SYSTEM.INI file's [386Enh]
section:
Example:
COM3IRQ=-1
