TCP PAD Timeout
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.
15 – 255 60 Seconds

Escape Guard Time
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.
