STB Status Byte Query

Figure 7-265 STB Syntax

The STB command returns to the controller the decimal equivalent of

the bits set in the status byte (see the RQS and SRQ commands). STB is

equivalent to a serial poll command. The RQS and associated bits are

cleared in the same way that a serial poll command would clear them.

For more information, refer to Chapter 5.
