This query returns a formatted numeric value corresponding to the SCPI version
number for which the instrument complies.
These queries return information about the instrument firmware’s available
connections. If a connection is not available, the returned value is -1.
This is only useful if there is more than one Keysight module connected to a PC,
otherwise one would normally use the default connections (HiSLIP and VXI-11
instrument number 0, socket port 5025, telnet port 5024)
One can never be sure if a socket port is already in use, so one could e.g. specify a
HiSLIP number on the command line (AgM8190Firmware.exe /AutoID /i 5
/FallBack /r …) and let the firmware find an unused socket port. Then this
socket port can be queried using the HiSLIP connection.
