S-Register Reference
S0 Ring to Answer After
The contents of register S0 sets the number of rings required before
the modem goes off-hook to answer an incoming call (auto answer).
The value can range from 0 to 255. ATS0=0 disables the auto-
answer function. The default is 0.
S1 Ring Counter
This register is read only. The value of S1 increments with each ring.
If no rings occur over a six-second interval, the register is cleared.
The value of S1 can range from 0 to 255. The default is 0. Limits are
country specific.
S2 AT Escape Character
Register S2 defines the ASCII character used in the Escape se-
quence. This command is used to return to command mode without
losing the connection with a remote modem. Default is S2=43,
which is the + character. Thus the default Escape sequence is
+++. ASCII values 127 and below can be used. To disable this
Escape sequence, set S2 equal to a value greater than 127.
S3 Command Line Termination Character
This register contains the ASCII value of the command line
terminating character (carriage return). The factory default value is
ASCII 13  the carriage return character. You can set register S3
to any value between 0 and 127.
