AT? - Read Selected S-Parameter
This command reads and displays the selected S-Parameter. An S-
Parameter can be selected by using the ATSn command.
Syntax
S=?
Result Codes
OK
For all arguments.
Sn - Read/Write S-Parameter
The modem selects an S-Parameter, performs an S-Parameter
read or write function, or reports the value of an S-Parameter.
n
Establishes S-Parameter n as the last register
accessed.
n=v
Sets S-Parameter n to the value v.
n?
Reports the value of S-Parameter n.
The parameter n can be omitted, in which case the last S-
Parameter accessed will be assumed. The S can be omitted for AT=
and AT?, in which case the last S-Parameter accessed will be
assumed.
For example:
ATS7 establishes S7 as the last accessed
register.
AT=40 sets the contents of the last register
accessed to 40.
ATS=20 sets the contents of the last register
accessed to 20.
If the number “n” is beyond the range of the S-Parameters
available, the modem will return the ERROR message. The value
“v” is “MOD”ed with 256. If the result is outside the range permitted
for a given S-Parameter the values will still be stored, but
functionally the lower and higher limits will be observed. Input and
output are always in decimal format. Note that some S-Parameters
are read-only.
