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 con-
     troller 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

     gpib(3), pcii(4), tnt4882(4)

HISTORY

     The gpib driver was written by Poul-Henning Kamp, and first appeared in FreeBSD 5.4.

FIREWIRE(4)						   BSD Kernel Interfaces Manual 					       FIREWIRE(4)

NAME

     firewire -- IEEE1394 High-performance Serial Bus

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device firewire

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   firewire_load="YES"

DESCRIPTION

     FreeBSD provides machine-independent bus support and raw drivers for firewire interfaces.

     The firewire driver consists of two layers: the controller and the bus layer.  The controller attaches to a physical bus (like pci(4)).  The
     firewire bus attaches to the controller.  Additional drivers can be attached to the bus.

     Up to 63 devices, including the host itself, can be attached to a firewire bus.  The root node is dynamically assigned with a PHY device
     function.	Also, the other firewire bus specific parameters, e.g., node ID, cycle master, isochronous resource manager and bus manager, are
     dynamically assigned, after bus reset is initiated.  On the firewire bus, every device is identified by an EUI 64 address.

     /dev/fwmem0.0

HISTORY

     The firewire driver first appeared in FreeBSD 5.0.

AUTHORS

     The firewire driver was written by Katsushi Kobayashi and Hidetoshi Shimokawa for the FreeBSD project.
