S-Registers Reference
S-Registers Definitions
S-registers generally affect how the AT commands perform. Contents of the regis-
ters can be displayed or modified when the modem is in command mode.
To display the value of an S-register:
TYPE: ATSn?
where n is the register number.
PRESS: Enter
To modify the value of an S-register:
TYPE: ATSn = r
where n is the register number, and r is the new register value.
PRESS: Enter
S0 Auto Answer Ring Number
This register determines the number of rings the modem will count before auto-
matically answering a call. Enter 0 (zero) if you do not want the modem to auto-
matically answer at all. When disabled, the modem can only answer with an ATA
command.
Range: 0 − 255
Default: 0
Units: rings
S1 Ring Counter
This register, Ring Counter, is read only. The value of S1 is incremented with each
ring. If no rings occur over a six second interval, this register is cleared.
Range: 0 − 255
Default: 0
Units: rings
S2 AT Escape Character (user defined)
This register determines the ASCII valued used for an escape sequence. The de-
fault is the + character. The escape sequence allows the modem to exit data mode
and enter command mode when on-line. Values greater than 127 disable the es-
cape sequence.
