sendiso - Man Page

send IEEE 1394 isochronous packets from dump file


sendiso [ options ] FILE


sendiso takes the dump file FILE as generated by dumpiso(1), extracts the packets and sends them as they were received (in the same order, with the same channel numbers) as fast as possible - timing of the original dump is not preserved.

This program does not allocate any isochronous resources but just starts sending.  It should not be used in live environments where it might interfere with properly set up isochronous transmissions, it is a debug and performance benchmarking tool.


-l,  --loop=COUNT

Send dump file COUNT times.  Defaults to 1.

-i,  --infinite

Send dump file in an endless loop.

-s,  --speed=SPEED

Send packets at speed SPEED, which can be given as 100, 200 and 400 (in Mbit/s) or abbreviated as 1, 2 and 4.  Defaults to 100.

-p,  --port=PORT

Choose port PORT for sending.  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.


None known.
