*STB?
Query
The *STB? query reads the contents of the 488.1 defined status
register (STB), and the Master Summary Status (MSS). The
sponse represents the values of bits 0 to 5 and 7 of the Status Byte
register and the MSS summary message.
The response to a *STB? query is identical to the response of a
serial poll except that the MSS summary message appears in bit 6
in place of the RQS message. Refer to Table 8, page 137 for further
details on the status register structure.
