S-Registers (ATSn=x)
Certain modem parameters are stored in memory locations called
S0=
S0 sets the number of the rings required before the modem automatically answers a call. Set “S0=0” to disable
S1=
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=
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=
S3 holds the decimal value of the Carriage Return <CR> character used as the command line and result code terminator (asynchronous operation only). The factory default is 013.
