Disabling Parallel Poll Responses

Disabling Parallel Poll Responses
The PPU (Parallel Poll Unconfigure) statement gives the controller the
capability of disabling the parallel poll responses of one or more devices on
the bus.
Example The following statement disables device 5 only:
PPOLL UNCONFIGURE 705
This statement disables all devices on interface select code 8 from
responding to a parallel poll:
PPOLL UNCONFIGURE 8
If no primary address is specified, all bus devices are disabled from
responding to a parallel poll. If a primary address is specified, only the
specified devices (which have the parallel poll configure capability) are
disabled.
