You will see a listing of your system's IRQs and the devices to which they
are assigned. If an IRQ is not present in this list, it indicates that Windows is
not currently using it and the IRQ is considered available.
Locate your modem in the list of devices. If a yellow exclamation point
appears over the modem's description, your modem is in conflict with
another device. Either your modem or the other device will have to be
reinstalled to another IRQ in order to resolve your conflict.
If a usable, free IRQ does not exist, you may need to remove, disable, or
relocate another device. Refer to that device's documentation for more
information about removing, disabling, or relocating it.
If Windows still fails to recognize your modem and it does not have a yellow
exclamation point next to its IRQ, or if your modem does not appear in the
list, your modem may not be installed properly. Try reinstalling the modem.
Windows NT 4.0:
Click Windows Start, Programs, Administrative Tools, and
Windows NT Diagnostics. Click the Resources tab and select IRQ. You will
see a listing of your system's IRQs and the devices to which they are
assigned. If an IRQ is not present in this list, it indicates that Windows is not
currently using it and the IRQ is considered available. Typically, modems
can use IRQ 3, 5, 7, 9, 10, 11, 12, or 15. Take note of an available IRQ that your
modem can use. Your modem should be assigned to one of these IRQs.
If a usable, free IRQ does not exist, you may need to remove, disable, or
relocate another device. Refer to that device's documentation for more
information about removing, disabling, or relocating it.
Possible solution:
You may be using a COM port that is either already in use or not configured
correctly. To work properly, this modem must be assigned to a free COM
port. Make sure that your COM port is not already in use by another device.
