Chapter 12 - Status Registers & Result Codes
S-Register Descriptions
In most bit-mapped S-registers, the default bit value is 0. Non-0 default values are
followed by an asterisk. In some cases, default values are shown in the refence column
preceded by +. Some bits are reserved for factory use and should not be changed.
Basic S-Registers "ATSn=x"
Command Function & Description +Ref.
S0= Set the number of rings on which the modem will answer. 0 value disable
auto-answer
+000
S1= Counts and stores number of rings from an incoming call +000
S2= Define escape code character, default ‘+’ (43 dec.). A value of 128-255
disables the escape code
+043
S3= Define ASCII Carriage Return +013
S4= Define ASCII Line Feed +010
S5= Define ASCII Backspace. A value of 128-255 disables the Backspace key’s
delete function
+008
S6= Set the number of seconds the modem waits before dialing if ‘X0’ or ‘X1’ is
selected. If a setting of ‘X2’ to ‘X7’ is selected, the modem will dial as soon
as it detects a dial tone. This register also sets the time-out interval for the “W”
dial modifier to wait for the dial tone. (See also S41b4)
+003
S7= Set duration, in number of seconds modem waits for a carrier +060
S8= Set duration, in seconds, for pause (,) option in Dial command and pause
between command re-executions for Repeat (>) command
+002
S9= Set duration, in tenths of a second of remote carrier signal before recognition
(Ignored if in non-FSK or half-duplex operation)
+006
S10= Set duration, in tenths of a second, modem waits after loss of carrier before
hanging up
+007
S11= Set duration and spacing, in milliseconds, of dialed Touch-Tones +070
Extended S-Registers "ATSn=x"
