As with subsystem commands, use a <space> to separate a
command mnemonic from subsequent parameters. Separate adjacent
parameters with a comma. Parameter types are explained later in
this subsection.

Syntax
Response messages can contain both commas and semicolons as
separators. When a single query command returns multiple values,
a comma separates each data item. When multiple queries are sent
in the same message, the groups of data items corresponding to each
query are separated by a semicolon. For example, the fictitious query
: QUERY
I?
:
QUERYZ?
might return a response message of:
<datai>,
<datal>
;
Cdata2>,
<data2>
Response data types are explained later in this subsection. Note that
<new line><-END> is always sent as a response message terminator.
