45.Sh DESCRIPTION
46The
47.Nm
48utility is designed to provide a way for users to access and control the
49FireWire subsystem.
50Without options,
51.Nm
52will output a list of devices those are/were connected to the bus.
53.Bl -tag -width indent
54.It Fl r
55Initiate bus reset.
56.It Fl t
57Show the topology map.
58.It Fl c Ar node
59Show the configuration ROM on the node.
60.It Fl d Ar node
61Hex dump of the configuration ROM.
62.It Fl o Ar node
63Send a link-on phy packet to the node.
64.It Fl s Ar node
65Write to RESET_START register on the node.
66.It Fl l Ar file
67Load hex dump file of the configuration ROM and parse it.
68.It Fl g Ar gap_count
69Broadcast gap_count by phy_config packet.
70.It Fl i Ar pri_req
71Set PRIORITY_BUDGET register on all supported nodes.
72.It Fl R Ar filename
73Receive DV stream and dump it to a file. Use Ctl-C to stop the receiving.
74Some DV cameras seem not to send the stream if a bus manager exits.
75If you cannot get the stream, try the following commands.
76.Bd -literal -offset indent
77sysctl hw.firewire.try_bmr=0; fwcontrol -r
78.Ed
79.Pp
80The resulting file contains raw DV data excluding isochronous header
81and CIP header. It can be handled by
82.Ic libdv
83in the
84.Xr dports 7
85collection.
86.It Fl S Ar filename
87Send a DV file as isochronous stream.

112.Ed
113.Pp
114Swap first and second 30 frames and send them to DV recorder.
115.Pp
116For PAL, replace 'bs=120000' with 'bs=144000'.
