3.5.3.7 S Parameters
Basic commands that begin with the letter “S” are known as “S-Parameters”. The number following
the “S” indicates the “parameter number” being referenced. If the number is not recognized as a valid
parameter number, an ERROR result code is issued.
If no value is given for the subparameter of an S-Parameter, an ERROR result code will be issued
and the stored value left unchanged.
Note: what follows is a special way to select and set an S-parameter:
1. ATSn selects n as current parameter number. If the value of n is in the range (0, 2,
3, 4, 5, 7, 10, 12, 25, 30, 38), this command establishes Sn as last selected parameter.
Every value out of this range and less than 256 can be used but has no meaning and is
maintained only for backward compatibility with landline modems.
2. AT= or ATS= set the contents of the selected S-parameter
Example:
ATS7 establishes S7 as last selected parameter.
AT=40 sets the content of S7 to 40
ATS=15 sets the content of S7 to 15.
3. AT? returns the current value of the last S-parameter accessed
