information, as the installation using jumper shunts is similar for
Windows NT, 95, and 98.
If Plug-and-Play fails to install the modem, you need to determine IRQ
availability. Right-click the My Computer icon on your desktop. Click
Properties, and then the Device Manager tab. Double-click the
Computer icon at the top of the device list. You will now 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 doesn't
appear in the list, another problem exists, and you may need to call U.S.
Robotics Technical Support.
Windows NT Turn off your computer and physically remove the
modem. Restart your computer, and check for an available IRQ by clicking
Windows Start, Programs, Administrative Tools , and Windows NT

available IRQ that your modem can use. Your modem should be jumpered
to one of these IRQs. If there are no IRQs available, you may have to
remove, disable, or relocate another device in order to free an IRQ for use
by your modem. Refer to that device's documentation for more
information about removing, disabling, or relocating it.
Possible solution:
You may be using a COM port address that is either already in use or not
configured correctly. To work properly, this modem needs to be assigned
to a free COM port.
Windows 2000

another modem. Click Windows Start, Settings, and Control Panel,
