Status Reporting Commands
:STATus:QUEStionable[:EVENt][?]
Reads the event register in the questionable status group. It’s a read-only
register. Once a bit is set, it remains set until cleared by this command or
*CLS command. A query of the register returns a decimal value which
corresponds to the binary-weighted sum of all bits set in the register.
