# dumpiso(1)

dump IEEE 1394 isochronous channel packets

## NAME

dumpiso - dump IEEE 1394 isochronous channel packets

## SYNOPSIS

**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)](/isodump/5.md).  The dumped packets can be sent out again with [**sendiso**(1)](/sendiso/1.md).

## 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.
