I think you need to either print cs before you close the socket or make sure that cs is force (~computed) before you close the socket as laziness makes it get evaluated when you call print cs rather than when you call hGetLine. In other words, you try to read from the socket after you've closed it.

hGetLine, unlike hGetContents, has a strict semantics. actually, hGetContents is only lazy i/o operation, everything else (hGetChar, hGetBuf, hGetArray) is strict -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
