3.3.3 S-PARAMETER DEFINITIONS
3.3.3.1 S0 - Number of Rings to Auto-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
3.3.3.2 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
3.3.3.3 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 (+)
3.3.3.4 S3 - Carriage Return Character
S3 sets the command line and result code terminator character. Pertains to asynchronous operation only.
Range: 0-127, ASCII decimal
Default: 13 (Carriage Return)
3.3.3.5 S4 - Line Feed Character
S4 sets the character recognized as a line feed. Pertains to asynchronous operation only. The Line Feed control character is
output after the Carriage Return control character if verbose result codes are used.
Range: 0-127, ASCII decimal
Default: 10 (Line Feed)
3.3.3.6 S5 - Backspace Character
S5 sets the character recognized as a backspace. Pertains to asynchronous operation only. The modem will not recognize
the Backspace character if it is set to a value that is greater than 32 ASCII. This character can be used to edit a command
line. When the echo command is enabled, the modem echoes back to the local DTE the Backspace character, an ASCII
space character and a second Backspace character; this means a total of three characters are transmitted each time the
modem processes the Backspace character.
Range: 0-32, ASCII decimal
Default: 8 (Backspace)
