The Common Commands

*OPC

Syntax	*OPC
Definition	The instrument parses and executes all
	program message units in the input queue and
	sets the operation complete bit in the standard
	event status register (ESR). This command can
	be used to avoid filling the input queue before
	the previous commands have finished
	executing.

*OPC?

This query causes all the program messages in the input queue to be parsed and executed. Once it has completed it places an ASCII ’1’ in the output queue. There is a short delay between interpreting the command and putting the ’1’ in the queue.
