Brave man - you're  the first to try out this mechanism for real:-)

Some shell's do have slightly different syntax than what the example
script in the man-page shows.  You could try just echo'ing the input
parameters to some file and see what they are. Like

   echo "Input 1: $1" > /tmp/params.txt
   echo "Input 2: $2" >>/tmp/params.txt
   echo "Input 3: $3" >>/tmp/params.txt

at the top of your script (before they get put into the $FNAME etc).

Something in the back of my head says: Could you try putting the
input params inside curly brackets ? Instead of 

             HOSTNAME="$1"
             TESTNAME="$2"
             FNAME="$3"

try
             HOSTNAME="${1}"
             TESTNAME="${2}"
             FNAME="${3}"
