-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 .Fx 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).
