STATUS
*PRE
Command/Query
DESCRIPTION The *PRE command sets the PaRallel poll Enable register (PRE).
The lowest eight bits of the Parallel Poll Register (PPR) are
composed of the STB bits. *PRE allows you to specify which bit(s)
of the parallel poll register will affect the ‘ist’ individual status bit.
The *PRE? query reads the contents of the PRE register. The
response is a decimal number that corresponds to the binary sum of
the register bits.
