Individual Status Query

The individual status query allows the programmer to read the state of the IEEE
488.1 ist (individual status) message without performing a parallel poll. The query
returns a "1" or "0."

The ist message is formed by ANDing the bits in the Parallel Poll Enable Register
(*PRE) with the Status Byte and then ORing the result. In other words, the ist is
TRUE if any of bits of the Parallel Poll Enable Register AND'ed with the Status Byte
are TRUE.

*IST?

The Operation Complete command causes the power supply to generate the
operation complete message in the Standard Event Status Register when all pending
operations have been finished.
