ibppc — parallel poll configure (board or device)
#include <gpib/ib.h>
int ibppc( | ud, | |
configuration) ; |
int ud
;int configuration
; Configures the parallel poll response of the device or board specified
by ud
. The configuration
should either be set to the 'PPD' constant to disable parallel poll
responses, or set to the return value of the
PPE_byte() inline
function to enable and
configure the parallel poll response.
If ud
is a device descriptor then
the device will be remotely configured by the controller.
If ud
is a board descriptor then
the board will be locally configured. Note, in order to do a local
parallel poll configuration IbcPP2 must be set using
ibconfig().
IEEE 488.2 prohibits local parallel poll configuration (IEEE 488.1 PP2 subset),
requiring support for remote parallel poll configuration (IEEE 488.1 PP1 subset)
instead.
After configuring the parallel poll response of devices on a bus, you may use ibrpp() to parallel poll the devices.
The value of ibsta is returned.
