Hmmm - while I believe the patch handles raw mode ok,
I also believe that Eric's remarks about cooked
mode were correct. I have no easy solution for
cooked mode, however. This means that with or without
patch, cooked mode is handled incorrectly.

It would be better to check for cooked mode and
return an error (unsupported).
