NAME

     gpib — General-Purpose Instrument Bus (GPIB) driver

SYNOPSIS

     Either of the pcii(4) or tnt4882(4) drivers use this driver as the backend.

DESCRIPTION

     The gpib 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.

FILES

     /dev/gpibNib   Main device node to access the driver.

     /dev/gpibNl    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.
