Chapter 4 - Troubleshooting

This chapter describes common problems you may have with your modem and how to solve them. If you

are unable to make a successful connection, or if you experience data loss or garbled characters during a

connection, use the Initial Checklist below to begin the troubleshooting process. If the problem is not

resolved after going through the Initial Checklist, review the Common Problems section for further

troubleshooting recommendations. If you are still unable to make a successful connection, refer to the

Initial Checklist

The following checklist will help to ensure the modem has been properly set up.

• Make sure the COM port you chose during setup matches the COM port set in your communications

software. See Chapter 2 for more information.

• Check that the phone cord between the modem’s jack and the wall jack is undamaged and firmly

connected to both.

• Retry whatever action was not working.

• If it still does not work, check the following section for a description and possible solution to your

problem.

Common Problems

The following is a list of common problems associated with using a modem:

• The modem does not respond to commands.

• The modem dials but cannot make a connection.

• The modem disconnects while online.

• The modem cannot connect when answering.

• File transfer appears slower than it should be.

• Data is being lost.

• Garbage characters display on the monitor.

• Fax and communications software won’t run at the same time.

Use the following instructions to guide you through troubleshooting these problems before contacting

Technical Support:

The modem does not respond to commands

• Verify that your data communication program is in terminal mode; then type AT and press Enter. If

the response is not OK, reset your modem by sending an ATZ or AT&F command in terminal mode.

If using legacy software (software designed for an older operating system), make sure the

initialization string includes &F as the first command to cancel any leftover commands that could

interfere with the modem’s operation.

• If the response is not OK, the problem may still be in the communications software. Verify that you

properly configured the port in your communications software. Most legacy (prior to Windows 95)

communications programs connect to the COM port when the software loads and remain connected
