S-Parameter Definitions
S0 - Number of Rings to Automatic Answer
S0 sets the number of the rings required before the modem automatically answers
a call.
Setting this parameter to zero disables auto-answer mode.
Range: 0-255 rings
Default: 0
S1 - Ring Counter
S1 is incremented each time the modem detects a ring signal on the telephone
line. S1 is cleared if no rings occur over an eight second interval. Range: 0-255
rings Default: 0
S2 - Escape Character
S2 holds the decimal value of the ASCII character used as the escape character.
The default value corresponds to an ASCII '+'. A value over 127 disables the
escape process, i.e., no escape character will be recognized.
Range: 0-255, ASCII decimal
Default: 43 (+)
S3 - Line Termination Character
S3 sets the decimal value of the command line and result code terminator
character. Pertains to asynchronous operation only.
Range: 0-127, ASCII decimal
Default: 13 (Carriage Return)
S4 - Response Formatting Character
S4 sets the decimal value of the character generated by the modem as part of the
header, trailer, and terminator for result codes and information text, along with the
S3 parameter (see the description of the V parameter for usage). If the value of S4
is changed in a command line, the result code issued in response to that
command line will use the new value of S4.
The Response Formatting character is output after the Line Termination character
if verbose result codes are used.
Range: 0-127, ASCII decimal
