ATSn
Read/Write S-Register
The modem selects an S-Register, performs an S-Register read or
write function, or reports the value of an S-Register.
Sn
Sn=v
Sn=?
The parameter n can be omitted, in which case the last S-Register
accessed will be assumed. The S can be omitted for AT=and AT?, in which case
the S-Register accessed will be assumed.
For example:
ATS7
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-Registers 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-Register the values will still be stored, but functionally the lower and higher
limits will be observed. Input and output are always indecimal format. Note that
some S Registers are read-only.
In some cases, writing to the S-Register will appear to be accepted
but the value will not actually be written.
Due to country restrictions, some commands will be acceptd, but the
value may be limited and replaced by a maximum or minimum value.
ATT
Set Tone Dial Default

countries.
