Here, thought i could use this myself for testing ethernet projects.....
I've attached the source code and exe file, i use Delphi 5, see no point in upgrading lol, everything i do is not really sophisticated but good for small utilities and tools, feel free to compile it yourself if you have Delphi it uses TClientSocket (comes with Delphi 4 - 7 i think)....
Hope someone finds it useful.. simply stick in the IP address and Port and connect via TCP IP and send whatever from the send button.
