Troubleshooting Modem Installation
Review this section if any of the following problems occur:
 Modem initialization errors occur when attempting to dial-out using
a communications application.
 Connection fails or other problems occur.
It may be necessary to define a modem type within your communications
application. If the Intel modem is not listed, choose a Generic Hayes
compatible device.
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:
1Some computers use a hardware setup utility to configure the infrared
port in the BIOS. See your computer documentation.
2To disable the infrared communications port in Windows 95, go to
Device Manager tab under System in the Control Panel.
3Double-click the Ports (COM & LPT) entry and the IR Serial Port
entry. Check the Disable in this Hardware Profile option to disable the
device.

2-6 Intel®PRO/100 LAN+Modem56 CardBus Adapter User’s Guide
4 You may also need to comment out any "device=" lines containing
TRANXIT in the SYSTEM.INI file. Use a semicolin at the beginning
of the line to comment out the line.
Use the Modem Diagnostics Tool to verify the computer-to-modem
interface.
1In the Modems option in Control Panel, click Diagnostics.
2In Diagnostics properties, highlight the COM port associated with the
Intel modem and click the More Info button. This causes Windows 95
and 98 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 Intel modem
may return ERROR for some AT commands that are not
supported. This does not indicate a failure.
3The Record a Log File option in the Modems option can also help
identify modem problems by recording modem commands and
responses in a MODEMLOG.TXT file. To create the
MODEMLOG.TXT file, go to Control Panel, Modems, Properties,
Connection, Advanced. In the Advanced Connection Settings window,
place a check mark in the Record a log file option box. A
MODEMLOG.TXT file will be created in the C:\WINDOWS
directory the next time the modem is used.
