3 AT Commands, Result Codes, and S-Registers

S-Registers

S-registers generally affect how the AT commands perform. You can read or alter the contents of an S-register by using the S command (see AT Commands).

Register	Unit	Range	Default	Description
S0	rings	0, 1–255	0	Sets the number of rings before the
				modem answers. ATS0=0 disables
				auto-answer completely.
S1	rings	0–255	0	Counts the number of rings that have
				occurred.
S2	decimal	0–127	43 (+)	Sets ASCII code for the escape
		128–255		character. Values greater than 127
				disable the escape sequence.
S3	decimal	0–127	13 (^M)	Sets ASCII code for the carriage
				return character.
S4	decimal	0–127	10 (^J)	Sets ASCII code for the line feed
				character.
S5	decimal	0–32	8 (^H)	Sets ASCII code for the backspace
		33–127		character. Values greater than 32
				disable the backspace character.
S6	seconds	2–65*	2*	Sets the time the modem waits after it
				goes off-hook before it begins to dial
				the telephone number.
S7	seconds	1–255*	50*	Sets the time the modem waits for a
				carrier signal before aborting a call.
				Also sets the wait for silence time for
				the @ dial modifier.
S8	seconds	0–65	2	Sets the length of a pause caused by a
				comma character in a dialing com-
				mand.
S10	100 ms	1–254	20	Sets how long a carrier signal must be
				lost before the modem disconnects.

Note: These values may be different outside North America.
