I believe it depends on the terminal that you are emulating. It looks like the most common use is to interrupt any process that is currently running.

Some quick google searching seems to indicate that this key is no longer used in most terminal emulators (for example the IBM AS400 emulator I work with uses the Esc key instead). I would advise checking the documentation for whichever terminal you are using to see the specific behavior that you would expect in your environment.
