12 Escape Sequence Guard Time
Range: 0-10000 ms
Default: 990 ms
The Escape Sequence Guard Time is the time delay required immediately before and after entering an
escape sequence.
For your modem to distinguish the escape sequence from ordinary data, there must be a period of
silence both before and after the escape sequence is entered. If the Escape Sequence Guard Time is
one second and the escape sequence character has been defined as ‘+’, for the modem to
recognise an escape sequence you must maintain silence on the line for one second, then type
‘+++’ in rapid succession, and then maintain another second’s silence.
The guard time is in units of milliseconds (or 1/1000 of a second).
‘S’ register 12 is also used to time the period between the escape sequence characters
as they are typed. If the period between the first and second escape characters or
second and third escape characters being entered is greater than the value in S Register
12, the modem will not recognise the escape sequence.
Examples
ATS12=990
Maintain silence on the line for 0.99 seconds before and after entering
the escape sequence
