The any-key abort is useful if the number dialed does not
answer. Otherwise, if you do not press a key, the call will
time-out and disconnect based on the settings of other
configuration options, such as S-Register 7.
The ATH command is another method of disconnecting. Once
your call is complete, enter online Command mode and issue an
ATH command to make your modem hang up, or go on-hook.
The format and procedure for an ATH command is:
TYPE: +++
To exit Data mode and enter online Command mode
TYPE: ATH or ATH0
PRESS: Enter
The modem disconnects.
A third, and more subtle approach to hanging up a call, is to
make sure that the &D command is set to &D2 (the factory
default setting which is standard EIA RS-232 operation). This
will allow your communications software to drop the DTR signal
to the modem and force the modem to disconnect the call. This
method is often used by communications software.
Also note that your modem will automatically disconnect when
the remote modem hangs up.
If you would like to know more about disconnecting a call, refer
to the following commands in Chapter 4: +++ (escape
sequence), O (Return Online to Data Mode), X (Extended
Result Codes, Dial Tone Detect, Busy Tone Detect), Y (Long
Space Disconnect), &D (DTR Action), \N (Error Control Mode),
\T (No Data Disconnect Timer), S7 (No Answer Time-out), S10
(No Carrier Disconnect), and S85 (Fast Disconnect).
