Echo Troubleshooting
Problem:
Each character you type appears twice or no
characters appear at all during data mode.
Solution:
Make sure that your software is in full-duplex
mode when you make a call. If the remote
modem is not also in full duplex mode, change
to terminal mode, type
AT E0
and press Enter.
Then turn on your communications software’s
local echo. Your software now echoes commands
during terminal mode and any typing performed
during data mode.
Dial Troubleshooting
Problem:
The modem does not automatically dial a call
when you send a Dial command.
Solution:
Make sure the modem speaker is turned on in
your software so that you can hear dialing
sounds. Also make sure that the phone line is
plugged in.
Make sure that your are dialing a valid phone
number, including any required dial prefixes.
If you are using tone dialing on a line that re-
quires pulse dialing, the line may not be able to
accept tone-dialed calls. Select Pulse dialing in
your software or include the P command in
place of T in your Dial command line to specify
pulse dialing.
Make sure software dialing prefix is ATDT (for
tone dialing) or ATDP (for pulse dialing).
Make sure your communications software and
modem are configured for the same COM port.
