Either of the pcii(4)
use this driver as the backend.
driver provides support for driving an IEEE-488 bus,
also called IEC-625 (or just "IEC bus"), or HP-IB (Hewlett Packard
Instrument Bus), or GPIB (General Purpose Instrument Bus). The device can
become either a listener, talker, controller, and in particular a master
controller on the bus.
- Main device node to access the driver.
- Listen-only entry to the driver. When opening, an
instrument can send data to this device on the bus in an unaddressed mode,
for example hard-copy printer data.
