If ComTest recommended COM2/IRQ3
Write "COM2" and "IRQ3" in the spaces
provided on the first page of this manual. Go to
"How to Change the Modem's Settings" on
page 10.
If ComTest recommended COM3/IRQ4
or COM4/IRQ3
Do not use either of these settings. While the
COM port part of the setting is acceptable
(ComTest only recommends COM ports that
are not being used), the IRQ part of the setting
is not acceptable. When ComTest
recommends either COM3/IRQ4 or
COM4/IRQ3, the IRQ in the setting is being
used by another accessory. You could use the

risk that the modem and/or the other accessory
sharing the IRQ might not work properly.
