S-registers
S0 – Number of Rings to Auto-Answer
S0 sets the number of the rings required before the modem automatically answers a call.
Setting this register to zero disables auto-answer mode.
Range: 0–255 rings
Default: 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
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 – Carriage Return Character
S3 sets the command line and result code terminator character.
Range: 0–127, ASCII decimal
Default: 13
(Carriage Return)
S4 – Line Feed Character
S4 sets the character recognized as a line feed. 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)
S5 – Backspace Character
S5 sets the character recognized as a backspace. 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)
