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.


SEE ALSO

     FreeBSD 5.4.
