56K Faxmodem Owner’s Manual
Problem:
The modem takes too long to hang up at the
end of a call.
Solution:
Your modem may not be receiving the required
initialization string, which should include the
&C1 setting, from your software.
In your software, make sure you have selected
your modem. If not, select it and exit and restart
your communications software. If you still have
problems, add &C1 to the initialization string
and exit and restart the software. (See “Tips for
Selecting Setup Options” in Chapter 2.)
Problem:
You type an AT command line and press
Enter, but your modem fails to execute the
command line.
Solution:
Be sure you type
AT
at the beginning of the
command line.
Make sure the communications software is con-
figured for the same COM port as your modem.
For example, if the modem is configured for
COM4, the software should be configured for
COM4.
Be sure your modem is not in data mode when
you type the command. Use the escape
character sequence to switch to terminal mode.
(The default escape sequence is to wait at least
one second, type +++, and wait another second
or more.)
Problem:
No response appears after executing a
command.
Solution:
If you typed a command but did not receive an
OK response from your modem:
Make sure the communications software and
modem are configured for the same COM port.
The E0 and Q1 commands may be in effect, dis-
abling echo and responses. Verify this with the
&V command. To enable echo and responses
type AT E1 Q0 and press Enter.
