6.1.9. Overlapped Processing
The due to the nature of switching operations, all commands are
processed sequentially. There is no overlapped processing. As
such the following commands are included for compatibility with
other 488.2 devices. They provide no added functionality beyond
performing their required functions in as little time as possible.
Per the standard these operations wait while the no-operation-
pending flag is false. On devices that have only sequential
operations, the standard calls for this flag to always be true.
*WAI – does not have any effect.
*OPC? – returns “1”.
*OPC – sets the OPC bit in the ESR. The values of ESB and
MSS are re-evaluated.
