TCP PAD Timeout

15 – 255

60

Seconds

 

This is a timer for the TCP connection (both originate and

 

 

 

 

answer) and disconnection handshake operations.

 

 

 

For originate connections this timer must also allow for network registration if the modem is not registered prior to the Dial command.

For disconnects, if the timer expires prior to a graceful TCP disconnection, the modem will disconnect without completing the handshake.

Escape Guard Time

0 – 255

0

0.02s

This register determines the minimum idle period before and after the entry of the escape code sequence (+++ or as defined in S2). Also, it defines the maximum period, in fiftieths of a second, allowed between consecutive asynchronous escape characters (S2) for the time dependent escape sequence to be considered valid.

If this register is set to 0, the guard time of the escape sequence is disabled.
