[Haskell-cafe] Help with terminal IO

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. -- ryan
