[Haskell-cafe] Character I/O

I ran the following program:
>module Main where
>main = do
> putStrLn "Key"
> c <- getChar
> print c
Unfortunately, it doesn't do what I was hoping. Specifically, it only
returns any data when I hit [return]. It also seems to be giving me a
command history somehow. Special keys (e.g., arrow keys, backspace,
escape) don't get through to the application.
I'm trying to write a program that uses individual keys as commands.
What's the correct way to get this to work?
