|Ah, I have got it working!
What I have done is added a '\r' (or '\n') to the end of the string of data being sent from my Server program (written in VS2010 C#). The data is now seen by the Client when the app is run on BOTH the Local & Remote Machine.
I dont need to '\r' character when sending FROM Client TO Server for the server to see the data.
Don't know why my program worked with VS2010 (client & server), but now has to be modded, to work with VS2015 Client. Guess as it now works, I am not too bothered!
Thanks for your time & help!
