Troubleshooting
Your MT2834ZPX was thoroughly tested at the factory before it was
shipped. If you are unable to make a successful connection or if you
experience data loss or garbled characters during your connection, it
is possible that the modem is defective. However, it is more likely that
the source of your problem lies elsewhere. Problems you may
encounter include the following:
• 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 is slower than it should be.
• Losing data.
• Getting garbage characters on the monitor.
• Can’t run fax and communications software at the same time.
If you experience problems, please check the following possibilities
before calling Tech Support (see Chapter 7).
The Modem Does Not Respond to Commands
• Make sure you are issuing the modem commands from the data
communications software, either manually in terminal mode or
automatically by configuring the software. (You cannot send
commands to the modem from the DOS prompt.)
• 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
your phonebook entry or session settings.
• Try resetting your modem by turning it off and on. Make sure there
is a reset command (&F) in your initialization string, or your
modem may not initialize correctly.
• 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. Not all
communications programs connect to the COM port automatically.
