S-Registers (ATSn=x)
Certain modem parameters are stored in memory
locations called S-Registers. Use the
S command
to read or alter the contents of S-Registers.
S0= 0-255
S0 sets the number of the rings required before the
modem automatically answers a call. Set “S0=0” to
disable auto-answer mode. The factory default
setting is 0.
S1= 0-255
S1counts the incoming rings and stores the value to
this register. The value of this register is
incremented with each ring. If no rings occur over an
8 seconds interval, this register is cleared. User can
read but should not change this value. The factory
default setting is 0.
S2= 0-255
S2 holds the decimal value of the ASCII character
used as the escape character. The default value
(043) corresponds to an ASCII character “+” (plus).
A value of 128 to 255 disables the escape process,
i.e., no escape character will be recognized 043.
S3= 0-127
S3 holds the decimal value of the Carriage Return
character used as the command line and
result code terminator (asynchronous operation
only). The factory default is 013.
