If you encounter problems while using your modem, please read
this chapter. If you can not resolve your difficulties after reading
this chapter, contact your dealer or vendor for assistance.
Modem does not respond to commands.
1.
Make sure the communication software is configured with
the correct COM port and IRQ setting (same COM port and
IRQ setting as the modem). Your communication software
will not be able to send or receive any data if it is not
configured to match the COM and IRQ settings for the
modem.
2.
Make sure that your modem is initialized correctly. Your
modem may have been improperly initialized by the software
because you have selected an incorrect modem type. You
may also be prompted to enter an initialization string by the
software. Use AT&F as your initialization string.
Modem does not dial.
1.
Make sure the modem is connected to a working phone line.
Replace the modem with a working phone to ensure that the
phone line is working.
Modem dials but does not connect.
1.
Make sure the IRQ setting is identical on both the modem
and the software.
2.
Make sure the phone line is working properly. A noisy line
will prevent proper modem operation.
