[Haskell-cafe] Help with terminal IO

[Ryan Ingram]

I was hoping that hSetBuffering would turn off the line buffering for stdin,
but it doesn't seem to work.

----
module Main where
import System.IO

main :: IO ()
main = do
    hSetBuffering stdin NoBuffering
    hSetBuffering stdout NoBuffering

    hPutChar stdout '>'
    c <- hGetChar stdin
    hPutChar stdout '<'
----

This program should terminate immediately after the first character is typed
into the terminal, but it waits until I type a newline.  It also looks like
it's using GNU readline (it handles the up & down arrow keys.)

How do I turn this off and use raw character-based IO?  I'm using GHC6.6 on
Win32 if that makes a difference.
