*OPC?
The *OPC? command monitors the pending operations, and places ASCII character
1 into the output queue when all pending operations are completed. Also this
command sets/clears the operation complete (OPC) bit in the standard event status
register as follows:
• If there are no pending operations, sets the OPC bit to 1.
• If there are any pending operations, sets the OPC bit to 0.
The bit will be set to 1 when all pending operations are completed.
*OPC?
1<CR/LF^EOI>
No response will be returned until all pending operations are completed.
