2. Select 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, select Diagnostics.
2. In Diagnostics properties, highlight the COM port associated
with the IBM modem and select 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 IBM
modem may return ERROR for some AT commands that
are not supported. This does not indicate a failure.
A log file can be useful to help identify modem problems by
recording modem commands and responses. Windows 95 and
98 have slightly different procedures for creating and maintaining
a log file:
1. In Windows 95, go to Control Panel Modems
Properties Connection Advanced.
2. In the Advanced Connection Settings window, place a check
mark in the Record a log file option box.
Note:
A file named MODEMLOG.TXT will be created in the
C:\WINDOWS directory the next time the modem is
used.
