ibsic
Name
ibsic -- perform interface clear (board)
Description
ibsic() resets the GPIB bus by asserting the 'interface clear' (IFC)
bus line
for a duration of at least 100 microseconds. The board specified
by ud must be the system controller
in order to assert IFC. The interface clear causes all devices
to untalk and unlisten, puts them into
serial poll disabled state (don't worry, you will still be able
to conduct serial polls), and the board becomes
controller-in-charge.
Return value
The value of ibsta is returned.
