[Haskell-cafe] getChar

is there a version of getChar that doesn't buffer keyboard input until enter
is pressed?

specialReadln :: IO String
specialReadln = do c ← getChar
                   if c == '#'
                     then do return []
                     else do cs ← specialReadln
                             return (c:cs)

I want the input process to terminate when '#' or any other specific key has
been pressed.

Best Regards,
