Chapter 6 - Solving Problems

51

Common Problems

You may encounter the following problems:

• The modem does not respond to commands.

• The modem dials but is unable to 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.

• There are garbage characters on the monitor.

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

If you experience problems, please check the following possibilities
before calling Technical Support (see Chapter 7).

The Modem Does Not Respond to
Commands

•

Make sure you are in terminal mode in your data communications
program, then type AT and press ENTER. If you get an 

OK

response, your connections are good and the problem likely is in
the connection description in your communications software.

•

Try resetting your modem by sending it an 

ATZ or AT&F command

in terminal mode. If you are 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 you don’t get an 

OK, the problem may still be in the

communications software. Make sure you have done whatever is
necessary in your software to make a port connection. Most legacy
communications programs connect to the COM port when the
software loads, and remain connected until the program terminates.
Some, however, can disconnect without exiting the program; if you
have one of these, try issuing the software’s connection command.
Also, if more than one communications program is open, they can
conflict with each other. Make sure all other communications
programs are closed, and then try again.
