Possible Solutions

How to Use the Windows 98 Modem Diagnostics Tool

  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 the modem, read responses from the modem, and display information about the modem and its COM port. The Port Information box should display the following information:
  3. A log file can be useful to help identify modem problems by recording modem commands and responses. Windows 98 creates a log file by default in the Windows directory, using a filename based on the modem device identifier, with a .LOG extension, such as "Xircom_CardBus_modem.log" (or a shortened version in MS-DOS). To continue adding information to the log file, place a check mark in the Append to Log option box in the Advanced Connection Settings window (use the path Control Panel, Modems, Properties, Connection, Advanced).

Windows NT Troubleshooting

Verify that you have Windows NT 4.0 Service Pack 5 (SP5) installed.

  7. Enter the location of the Xircom CD-ROM (for example, D:\), and click OK.
  8. Click Next.
  9. Refer to the list of ports you recorded from the Configure Modem PC Cards window earlier, and select the highest port on the list (COM5 or higher). Click  Next.
