Model 3830 S-Registers

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 + sign).

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.

S4 Line Feed Character

Determines ASCII value used as the line feed character.

Enter a value from 0±127 for the line feed character.

Factory setting is 10 (ASCII line feed).

S5 Backspace Character

Determines ASCII value used as the backspace (Backspace key). This character moves the cursor to the left and erases the previous character.

Enter a value from 0±127.

Factory setting is 08 (ASCII backspace).
