4.6.1 IEEE488.2 Register Model
Status byte register
The status byte register stores STB and RQS (MSS) messages as defined by the
IEEE488.1 standard. The status byte register can be read using IEEE488.1 serial
polling or IEEE488.2 common command *STB?.
When serial polling is carried out, bit 6 responds with the request service (RSQ).
The status byte value is not changed by serial polling.
The *STB? query makes the device transmit the contents of the status byte register
and the master summary status (MSS) summary message.
The *STB? query does not change the status byte, MSS, and RQS.
