NAME
     fwcontrol -- FireWire control utility

SYNOPSIS
     fwcontrol [-u bus_num] [-prt] [-c node] [-d node] [-o node] [-s node]
	       [-l file] [-g gap_count]	[-b pri_req] [-R filename]
	       [-S filename] [-m EUI64 | hostname]

DESCRIPTION
     The fwcontrol utility is designed to provide a way	for users to access
     and control the FreeBSD FireWire subsystem.  Without options, fwcontrol
     will output a list	of devices that	are/were connected to the bus.

     The following options are available:

     -u	bus_num
	     Specify the FireWire bus number to	be operated on.

     -r	     Initiate bus reset.

     -t	     Show the topology map.

     -p	     Dump PHY registers.

     -c	node
	     Show the configuration ROM	on the node.

     -d	node
	     Hex dump of the configuration ROM.

     -o	node
	     Send a link-on PHY	packet to the node.

     -s	node
	     Write to the RESET_START register on the node.

     -l	file
	     Load hex dump file	of the configuration ROM and parse it.

     -g	gap_count
	     Broadcast gap_count by phy_config packet.

     -i	pri_req
	     Set the PRIORITY_BUDGET register on all supported nodes.

     -R	filename
	     Receive DV	stream and dump	it to a	file.  Use Ctrl-C to stop the
	     receiving.	 Some DV cameras seem not to send the stream if	a bus
	     manager exits.  If	you cannot get the stream, try the following
	     commands:

		   sysctl hw.firewire.try_bmr=0
		   fwcontrol -r

	     The resulting file	contains raw DV	data excluding isochronous
	     header and	CIP header.  It	can be handled by libdv	in the FreeBSD
	     Ports Collection.

     -S	filename
	     Send a DV file as isochronous stream.

     -m	EUI64 |	hostname
	     Set default fwmem target. Hostname	will be	converted to EUI64
	     using eui64(5).

EXAMPLES
     Each DV frame has a fixed size and	it is easy to edit the frame order.

	   fwcontrol -R	original.dv

     Receive stream.

	   dd if=original.dv of=first.dv bs=120000 count=30

     Get first 30 frames(NTSC).

	   dd if=original.dv of=second.dv bs=120000 skip=30 count=30

     Get second	30 frames(NTSC).

	   cat second.dv first.dv | fwcontrol -S /dev/stdin

     Swap first	and second 30 frames and send them to DV recorder.

     For PAL, replace ``bs=120000'' with ``bs=144000''.
