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.

AT-TTE=U1,
 U2, U3 
Voltage 
Loop voltage after 
the connection is 
terminated. 
U3

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.
