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.

It adds content mappers, letting tools like Vue check non-standard files. One Vue project's type checks fell from 14.19 to 3.10 seconds. An editor issue remains open, and teams may need TypeScript 6 alongside 7.

AWS has made Continuum for code vulnerabilities generally available in two regions. The service proves exploitability by running real exploits in a sandbox, then opens fixes as pull requests. Published pricing charges per finding processed as well as per line of code, and practitioners are asking what would justify letting it merge fixes on its own.
