2.2.2 AT command S register set
The available S-Parameters are listed below and can be stored to the user profile by
entering the “AT&W” command.
The modem selects an S-Parameter, performs an S-Parameter read or write
function, or reports the value of an S-Parameter.
ATSn=v Set S-Parameter n to the value v.
ATSn? Reports the value of S-Parameter n
If the number “n” is outside of the range of the available S-Parameter or the value
“v” is outside the range permitted for the given S-Parameter, the mode will return the
ERROR message.
Some S-Parameters are read only.
S0
Number of Rings to Auto-Answer
S0 set the number of the rings required before the TA automatically answers a call.
Setting this parameter to “0” disables auto-answer mode.
S0 0: No automatic call acceptance, acceptance of an incoming call is
controlled by the data terminal (command ATA after RING)
1: Immediate call acceptance by the terminal adapter
2..n: Call acceptance through the terminal adapter after n "RING"
messages.
The serial status line "RI" will toggle during the active "RING" state uniformly
distributed according the half time of register S80.
Note: The time interval to display the incoming call (“RING” or “2”) can be
configured with the S-register S80.
S1
Ring Counter
S1 is incremented each time the TA signals the RING message to the serial
interface. This parameter is read only.
Note: If parameter S0 is set to “0” the ring counter is disabled.
