There are a number of examples out there - and they do work. So I'm 
slightly concerned that you found some which don't - it would be helpful 
if you could let us know which ones you tried without success. Hopefully 
that would lead to either answers to make them work for you, or changes 
to make them work for the next person who tries them.

You can find my version in RevOnline, under username "alextweedly" - the 
TCP version is called TCPApp1 and TCPApp2. TCPApp1 is basically a 
server, TCPApp2 basically a client - though they have been extended to 
allow asynchronous communication initiated by either side once the 
connection is open.

I'd encourage you to try the samples above, or to work with the ones you 
found earlier.

But - simple code -  the script for some object to do this could be as 
simple as


on mouseUp
  accept connections on port 5001 with message "gotConn"
end mouseUp

on gotConn pSocket
  read from socket pSocket until CR
  put it into field "myData"
  close socket pSocket
end gotConn
