Comma (,)
If a command requires multiple parameters, a comma must be used to separate parameters from one

either form and also in any combination of upper and lower case characters. Instrument responses,
however, are always in the short form, upper case.
If extra, redundant parameters are sent in a parameter list they are simply ignored. No error is
produced.

Data Types
