INTERNAL MODEM INSTALLATION WITH WINDOWS 3.X

If you do have a sound card, use
COM2/IRQ3. To use this setting, you have to
first disable your computer’s second serial port
(COM2). This is a pronged socket on the
back of your computer.
• Turn off your computer and unplug it from
the electrical outlet.
• Refer to your computer manufacturer’s
manual to find out which socket on the
back of your computer is the second serial
port.
• If you have something plugged into that
port, find out if you can plug it in
somewhere else. Any accessory plugged
into that port will not work after the port
has been disabled.
• Refer to your computer manufacturer’s
manual to find out how to disable the COM
port.
• Then return to this point in this manual to
continue.
After disabling COM2, you can use the
COM2/IRQ3 setting.
Write down “COM2” and “IRQ3” and go to
“How to Change the Modem’s Settings” on
page 10.
If ComTest reports that You do not have
any available COM ports and/or IRQs
We recommend you disable COM1 or
COM2. When you disable one of these COM
ports, you can use it and its default IRQ for
your modem.
