I think the second error is because there are nothing in $FILENAME because of the first error with basename. This is how to get basename another way: ${1##*/} (if you want it from $1).

I don't understand PATH and FILE in your script, they don't get any values?

I also think you must have a loop in the last part:

fi

should be:
Code:
...
else
  while [ -r ${SAVEPATH}${FILENAME}.$(date +%Y%m%d).$COUNT ]; do
    COUNT=`expr $COUNT + 1`
  done
  tail -n $2 $1 > ${PATH}${FILENAME}.$(date +%Y%m%d).$COUNT
fi

sendiso

sendiso(1)							  Linux IEEE 1394							sendiso(1)

NAME

       sendiso - send IEEE 1394 isochronous packets from dump file

SYNOPSIS

       sendiso [ options ] FILE

DESCRIPTION

       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.

OPTIONS

       -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.

BUGS

       None known.
