Sending strings between two computers via ethernet

A while ago I asked a question about using RS-232 communication with Java.  It seems as though I need to abandon that route because it no longer fits the desired system requirements.  Thanks to Nem for his advice on that one.

 

Now what I need to be able to do is send and receive strings between two computers connected via a network hub.  The computers in use would not be connected to the outside world and would only be communicating with each other at this point.

 

I need to be able to send a string like "auto" terminated with a carriage return when a button on a GUI is pressed by the user.  The GUI would then need to get back a string like "ok" or "err" also followed by a carriage return.

 

I am sure that I am making this much harder than I need to, so if anyone can help out it would appreciated.  For some reason I am having a lot of trouble absorbing how to use Java, so any help or explanations need to be in beginner terms.

 

Thanks.
