G5/G6-Family AT Commands User Manual Page
4.1.4 S, Bit Map Registers
This command reads/writes values of the S-registers. The module supports this command for various S
values, according to official specifications (ITU-I, ETSI, or manufacturer specific).
The Set command is allowed for
read/write S-registers, and not
allowed for read-only S-registers.
<current value of
S-register n>
OK
or:
+CME ERROR: <err>
The Test command for Sn is not
defined by ITU, and therefore is not
supported by the Module. The G5xx
returns an error.
The following table shows the different S-registers and their associated values.
Sets/gets number of rings before auto answer.
Sets/gets carriage return code character.
Sets/gets line feed code character.
Sets/gets command line editing character(backspace).
Sets/gets guard time (in units of 50 msec) for the
escape character during ODM connections
Note: S0 (Auto Answer) should work regardless of the DTR HW line state. This is a deviation from the
ITU V. 25-ter standard.
Example:
ATS0?
000
