S-Registers

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).

S0 0 Sets the number of rings on which to answer in Auto

Answer Mode. When set to 0, Auto Answer is

disabled.

S1 0 Counts and stores the number of rings from an

incoming call. (S0 must be greater than 0.)

S2 43 Stores the ASCII decimal code for the escape code

character. 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 waits

before dialling. If Xn is set to X2 or X4, this is the

time-out length if there isn't a dial tone.

S7 60 Sets the number of seconds the modem waits for a

carrier. May be set for much longer duration if, for

example, the modem is originating an international

connection.
