5	Status Registers & Result Codes
Register		Dec.	Function & Description	Default
S0=		0 - 255	Set the number of the rings required before the modem	000
			automatically answers a call. Set “S0=0” to disable auto-
			answer mode.
S1=		0 - 255	Count the incoming rings and store the value to this register.	000
			The value of this register is incremented with each ring. If no
			rings occur over an 8 sec. interval, this register is cleared.
			User can read but should not change this value.
S2=		0 - 255	S2 holds the decimal value of the ASCII character used as	043
			the escape character. The default value (043) corresponds to
			an ASCII character “+”. A value of 128 to 255 disables the
			escape process, i.e., no escape character will be recognized.
S3=		0 - 127	Hold the decimal value of the Carriage Return <CR>	013
			character used as the command line and result code
			terminator. Pertain to asynchronous operation only.
S4=		0 - 127	Hold the decimal value of the character recognized as a line	010
			feed. The line feed control character is output after the
			carriage return control character if verbose result code are
			used.
S5=		0 - 32,	Hold the decimal value of the character recognized as a	008
		127	backspace. The modem will not recognize the backspace
			character if this register is set to a value greater than 32.
S6=			Set the length of time, in seconds, that the modem must wait
			(minimum 2 seconds even if the value is less than 2) after
			going off-hook before dialing the first digit of the telephone
			number.
		2 - 65	For international version.	002
		4 - 65	For Japanese version.	004
S7=			Set the time, in seconds, that the modem must wait before
			hanging up because carrier is not detected.
		1 - 255	For international version.	050
		35 - 59	For Japanese version.	050
S8=		0 - 65	Set the time, in seconds, that the modem must pause when	002
			the “,” dial modifier is encountered in the dial string.
S10=		1 - 255	Set the length of time, in tenths of a second, that the modem	020
			waits before hanging up after a loss of carrier.
S11=		50 - 150	DTMF duration and inter digit delay. Set the duration and	095
			spacing, in mini-seconds, in DTMF touch tine dialing.
S12=		0 - 255	Define the maximum period, in 2-hundredths of a second,	050
			allowed between consecutive asynchronous escape character
			“+” (plus) for the escape sequence to be considered valid.
S28=		0 - 255	V.34 modulation en-/disabler. 0: disabled. 1- 255: enabled.	001
S30=		0 - 90	Inactivity timer. Set the length of time, in minutes, that the	000
			modem counts when there is no data flow in or out the DTE
			serial port. A connection is disengaged when the counter
			reaches the preset value. Set S30 =0 to disable the inactivity
			timer. For buffer mode only.
S36=			Negotiation fallback options.	007
