Listen on selected channels and dump IEEE 1394 packets received into the specified file, or to standard output if file is not specified. The current number of packets is written to standard error.
Set channels to listen to, as a single number or a range. Channel numbers can be from 0 to 63, and the option can be specified multiple times to add new channels each time. Without this option, dumpiso defaults to all channels.
Print usage information and exit.
Specify the IEEE 1394 port to receive on; only required if there is more than one on your system. The default is 0.
