5.12 *STB?
This query reads the Status Byte register, which contains the status summary bits and the
Output Queue MAV bit. Reading the Status Byte register does not clear it. The input
summary bits are cleared when the appropriate event registers are read (see chapter 7 for
more information). A serial poll also returns the value of the Status Byte register, except that
bit 6 returns Request for Service (RQS) instead of Master Status Summary (MSS). A serial
poll clears RQS, but not MSS. When MSS is set, it indicates that the source has one or more
reasons for requesting service.
