COMM_HEADER, CHDR
Description
The COMM_HEADER command controls the way the oscilloscope formats responses to queries. There
are three response formats; unless you request otherwise, the short response format is used.
This command does not affect the interpretation of messages sent to the oscilloscope, only responses to
queries. Headers can be sent in long or short form regardless of the COMM_HEADER setting.
