Response Message_____________________________________________
A response message is created after the syntax of a received query message
has been checked. The "HEADer" command can be used to select whether
there is a header.
Header ON
:FREQUENCY 1000
Header OFF
1000
(The current frequency is 1 kHz.)
The header is set to OFF when the power is turned on.
If some sort of error was generated when a query message was received, a
response message is not created for the query message.
