Registers | Western Telematic Data/FaxModem specs

6. S-Registers

Note: To change a setting, use the ATSr=n command, where r is the register and n is a decimal value from 0-255 (unless otherwise indicated).

Register	Default	Function

S0	1	Sets the number of rings on which to answer in Auto
		Answer Mode. When set to 0, Auto Answer is
		disabled. See DIP Switch 5 (Section 4.2).
S1	0	Counts and stores the number of rings from an
		incoming call. Register S0 must be greater than 0.
S2	43	Stores the ASCII decimal code for the escape code
		character. The default character is +. A value of 128-
		255 disables the escape code.
S3	13	Stores the ASCII code for the Carriage Return
		character. Valid range is 0-127.
S4	10	Stores the ASCII decimal code for the Line Feed
		character. Valid range is 0-127.
S5	8	Stores the ASCII decimal code for the Backspace
		character. A value of 128-255 disables the Backspace
		key's delete function.
S6	2	Sets the number of seconds the modem will wait
		before dialing. If Xn is set to X2 or X4, S6
		determines the timeout length when no dial tone is
		detected.
S7	60	Sets the number of seconds the modem will wait for a
		carrier. Often used to select a longer duration when
		the modem is originating an international connection.
S8	2	Sets the duration (in seconds) for the Dial command
		pause option (,).
S9	6	Determines the length of time (in tenths of a second)
		the remote modem’s carrier signal must continue in
		order to be recognized by the RMM.
S10	7	Sets the length of time (in tenths of a second) the
		modem will wait after loss of carrier before hanging
		up. Allows the modem to distinguish between a line
		hit (or other momentary break) from a true disconnect
		(hang up) by the remote modem.
