3 Status Registers
The Status Byte Register
The RQS bit is read and reset by a serial poll. The same bit position
(MSS) is read, non-destructively by the *STB? command. If you serial
poll bit 6 it is read as RQS, but if you send *STB it reads bit 6 as MSS.
For more information refer to IEEE 488.2 standards, section 11.
