This instrument implements the status model defined by IEEE 488.2 with regard
to the serial poll function using the service request line.
The term "event" refers to any occurrence that generates a service request.
The Status Byte Register contains information about the event registers and the
output queue. Required items are selected from this information by masking with
the Service Request Enable Register. When any bit selected by the mask is set,
bit 6 (MSS; the Master Summary Status) of the Status Byte Register is also set,
which generates an SRQ (Service Request) message and dispatches a service
request.
