running a script with tcpserver

Hi,
I want to make and run a simple script on port say 1234 which will 
print output of ls -l /usr/designs when user types "name" and
exit if something else.
Something like,

if [ "$1" = "name" ]
then
	ls -l /usr/designs
else
# echo "hello"
	exit
fi

But this does not work. I also tried running recordio before it. But all
it does it exits ( or prints hello ).
Any ideas why? I have a feeling that some extra characters are insrted
but no idea of knowing which
I am trying to connect to it from windows by using,
telnet 192.168.0.1 1234

Can someone help?
With warm regards,
-Payal
