S-Registers Reference

S-registers generally affect how the AT commands perform. Contents of the registers can be displayed or modified when the modem is in command mode.

To display the value of an S-register:

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

Range: 0−255

Default: 0

Units:rings

This register determines the number of rings the modem will count before automati- cally answering a call. Enter 0 (zero) if you do not want the modem to automatically answer at all. When disabled, the modem can only answer with an ATA command.

S1 Ring Counter

Range: 0−255

Default: 0

Units:rings

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.

S2 AT Escape Character (user defined)

Range: 0−255

Default: 43

Units:ASCII

This register determines the ASCII valued used for an escape sequence. The default 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 escape sequence.
