Description of the S Registers
S0 Number of Rings Before Automatically Answering (Auto Answer)
Register S0 specifies the number of rings after which your modem can
automatically respond to incoming calls.
Default: 0 (this value disables automatic answer).
S1 Count the Received Ring Signals
Register S1 counts the ring signals when you are called. If the value in this register
is greater than or equal to 1 and corresponds to the value in register S0, your
modem answers the call.
S2 Escape Character
Register S2 specifies the ASCII value of the escape character.
Default: 43
(This value corresponds to the ASCII character "+". This can be changed to any
value between 0 and 255. Values greater than 127 disable the escape function and
prevent reset to command mode.)
S3 Carriage Return
Register S3 defines the ASCII value of the carriage return character. This character
is used to terminate a command line and enables your modem to execute this line.
In addition, this character appears after the response that your modem sends to
you.
Default: 13
(Any ASCII value between 0 and 127 can be used. This may be required if you have
a non-standard device.)
S4 Line Feed
Register S4 specifies the ASCII value of the line feed character. Your modem sends
the character for the line feed after a carriage return character. If you wish to
prevent a line feed, set the value in this register to zero. It is not possible, however,
to disable a line feed character.
Default: 10
(Any ASCII value between 0 and 127 can be used.)
