12.16 AT*E2ESC M2M Escape Sequence Guard Time
Defines a guard time for the escape sequence in GPRS to return to on-
line command mode i.e. if +++AT<CR> is received either as part of the
data stream or a terminating string from the application and no further
data is received for the duration of the guard time the module will go
into on line command mode. This guards against the module
accidentally going into on line command mode. The verbose format of
