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.
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.
