Historically I've just used a small freebie web server that is easily configurable for which port it runs on for Windows based testing (from laptop). Once you've changed the port, a simple telnet to that port, type something (anything) and press enter and you will get HTML back. This obviously only works for TCP. Someone else may know of a specific tool that is designed to do just what you want and works for both TCP & UDP.

A port scanner is also useful for testing things like this.
