S-Register List

S-registers affect the operating parameters of the 3821Plus modem. These registers are applicable only when the DTE Dialer Type configuration option is set for AT. (See &Mn and &Qn commands.)

S-registers can be displayed and/or modified when the modem is in Command mode. To display the value of an S-register, issue the following command:

TYPE: ATSn?

Where: n is the register number.

PRESS: Enter

To modify the value of an S-register, issue the following command:

Table 4-2lists S-registerssupported by the 3821Plus. Not all S-register values are valid in all countries. See Appendix H.

NOTE

In some countries, the range of allowable values of some S-registers is restricted. If the DTE attempts to enter a restricted value, the modem answers OK, but it sets the register to the nearest allowable value. The DTE can check the actual value of the register with the Sn? command.

TYPE: ATSn=r

Where: n is the register number, and r is the new value.

PRESS: Enter

3821Plus S-Registers

S0 ± Auto-Answer Ring Number

Determines the number of rings the modem will count before automatically answering a call.

Enter zero (0) if you do not want the modem to automatically answer any calls. Otherwise, enter a value from 1±255 for the number of rings to count before answering. Note that if disabled, the modem can only answer with an ATA command.

The factory setting is 1.

NOTE: The default and permitted settings of this option are country-dependent. See Appendix H.

S2 ± AT Escape Character

Determines ASCII value used for escape sequence (+++) to enter Command mode from Data mode.

Enter a value from 0 to 127 for the escape character. Any value greater than 127 causes the modem to disable the escape sequence. When the escape sequence is disabled, the modem cannot return to Command mode until the call is disconnected.

Factory setting is 43 (ASCII + key).

S3 ± Carriage Return Character

Determines ASCII value used as the carriage return (Enter key). This character is used to end command lines and result codes.

Enter a value from 0 to 127 for the command end character.

Factory setting is 13 (ASCII carriage return).

NOTE: The &W command used to save this change must be on a separate line. This ensures both that the change is intentional, and that the DTE can enter the new character.
