S Registers

ATS12 Escape Sequence Guard Time

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 20 milliseconds (or 1/50 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.
