5.30 INQ
The INQ command inquires the instrument state. Note that when operating over RS232 or RS422
serial lines, it should be preceded with @@@@@@ <delay 400 ms> and a flush of the input
buffer in case the instrument is in power down or in a low power mode taking measurements.
Consult this section a description of the Instrument modes.
