*OPC
Syntax
*OPC
Description
The *OPC command sets the Operation Complete (OPC) bit of the
Standard Event Status Register (ESR) when the No Operation Pending flag
is TRUE (No Operation Pending flag is attached to each overlapped
command). Until that time, the controller may continue to parse and
execute previous commands. It is good technique, then, to periodically poll
the OPC bit to determine if the overlapped command has completed.
*OPC?
Syntax
*OPC?
Description
The *OPC? query returns the ASCII character "1" in the Output Queue
when the No Operation Pending flag is TRUE. At the same time, it also sets
the Message Available (MAV) bit in the Status Byte Register. The *OPC?
will not allow further execution of commands or queries until the No
Operation Pending flag is true, or receipt of a Device Clear (dcas) message,
or a power on.
