dumpiso - dump IEEE 1394 isochronous channel packets
dumpiso [ options ] [ FILE ]
DESCRIPTION
dumpiso listens on a selected range of channels and dumps all received packets into the file FILE or, if not
given, to standard output. While dumping, the current number of received packets is written to standard error
and updated with every packet.
It uses a simple file format for the dumps which is described in isodump(5). The dumped packets can be sent out
again with sendiso(1).
OPTIONS
-c, --channels=CHANNELS
Sets the channels to listen on. CHANNELS can be either a single number, in which case this is the only
channel to listen on, or a range of channels in the form X-Y. Channel numbers can range from 0 to 63.
You can give this option multiple times, new channels are added to the list of already set channels.
Defaults to all channels.
-p, --port=PORT
Choose port PORT for receiving. A port is a 1394 card or chip and represents one connected bus, therefore
this is only relevant when you have multiple of these. Defaults to 0.
-h, --help
Show help text and exit.
BUGS
None known.
