S-Register List

S-registers affect the operating parameters of 3800Plus
modems. S-registers are only applicable when the DTE
Dialer Type configuration option is set for AT. (See &Mn
command.)
Table 13-2 lists all S-registers supported by 3800Plus
modems. The first column lists the S-register. The second
column lists all possible values for that register. The third
column lists the key sequence used to enter the equivalent
from the front panel. Use the reference in this column to
locate commands in Chapter 8,
further description is necessary.
AT Command
S0 Auto-Answer Ring Number
Register determines 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.
Factory setting is 1.
S2 AT Escape Character
Register determines ASCII value used for escape sequence to enter
Command mode from Data mode.
Enter a value from 1 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 (+ key).
S3 Carriage Return Character
Register determines ASCII value used as the carriage return (Return 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 (carriage return key).
