Device Control and Status
–
Generic Commands
GCMD?
This command is a method of getting connected device. As well as returning the
device ‘Family’ type it also returns the model number.
As BLST only returns the ‘Family Type’ this function returns both this and the
model
connected as a string.
The query returns a CSV string where the first value is the Family Type of the
connected device followed by a string denoting the devices model number. If only
one value is returned, i.e. no comma and no second value, then a
‘family’ connecting
lead is plugged in but no device was detected connected to the lead.
