If your computer is equipped with an infrared communications port,
you may need to disable this port. These ports often use COM port
resources required for other communications devices. Disable the
infrared port both in the computer’s CMOS or BIOS setup program
and the Windows 95 Device Manager, as follows:
1
Some computers use a hardware setup utility to configure the
infrared port in the BIOS. See your computer documentation.
2
To disable the infrared communications port in Windows 95,
go to Device Manager tab under System in the Control Panel.
3
Double-click the Ports (COM & LPT) entry and the IR Serial
Port entry. Remove the check mark under Device Usage.
(Note: In Windows 95 version 950b or later check the Disable
in this Hardware Profile option to disable the device.)
Use the Modem Diagnostics Tool to verify the computer-to-
modem interface.
1
In the Modems option in Control Panel, click Diagnostics.
2
In Diagnostics properties, highlight the COM port associated
with the Xircom modem and click the More Info button. This
causes Windows to send commands to and read responses
from the modem and display information about the modem
and its COM port. The Port Information box should display the
following information:
•
The IRQ and I/O address of the modem’s COM port.
These should match the physical configuration of the port
or modem adapter.
•
Modem responses to various AT commands. The Xircom
modem may return ERROR for some AT commands that
are not supported. This does not indicate a failure.
