Assuming correct syntax...what do I do to echo out the stdout from the
"test-telnet.pl" command, while running a test against it?  IE,
# truly ugly pseudo-code
for i in `seq 250 254`
do
if (`test-telnet 111.222.333.$i <mac address>` | grep -c "Port 25" > 0)
then
  i++;
else
  echo out stdout from `test-telnet`
  break loop
end if
done
