INSYS Modem 336/56k 4.1 (UL) Functions
5.13.3 Remote Terminal Connection Abort
When the remote terminal aborts a connection, the modem
will immediately hang up.
In the registry S86, the value is set to 25.
Changing the loop voltage to detect the function – Remote
Terminal Connection Abort (U3) – can be set with the help of
AT commands.
ATS86=25
AT-TTE=U1, U2, U3
Voltage
Loop voltage after
the connection is
terminated.
U3
Loop voltage during
the connection
Time
Note: This detection is based on the change of the
loop voltage (AT-TTE=U1, U2, U3). It will not
work for all connections. ISDN phone systems in
particular often suppress the hang-up noise.
