character.

S-parameters
Commands that begin with the letter S constitute a special group of parameters known as
"S-parameters". These differ from other commands in important respects:
• 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.
• Immediately following this number, either a "?" or "=" character (IA5 3/15 or 3/13,
respectively) appears:
"?" is used to read the current value of the indicated S-parameter.
"=" is used to set the S-parameter to a new value. ""
