/* QUERY_WAVE_DATA - Outputs waveform records to the controller

/* READ_WAVE_DATA - The wave data consists of two parts: the
* header, and the actual waveform data followed by a
* New Line (NL) character.
The query data has the following
* format:
*
*
<header><waveform data block><NL>
*
* Where:
*
*
<header> = #800002048
(this is an example header)
*
* The "#8" may be stripped off of the header and the remaining
* numbers are the size, in bytes, of the waveform data block.
* The size can vary depending on the number of points acquired
* for the waveform which can be set using the
* ":WAVEFORM:POINTS" command.
You may then read that number
* of bytes from the oscilloscope; then, read the following NL
* character to terminate the query.
