Hi Pierre-Luc, Hans,

Yes. You need cfmakeraw() to do that (or do everything yourself). See
src/lib/libc/gen/termios.c to see what it does.

So what I'm interested in, is the following:

	"even that device is answering requests slower and slower until
	it stalls completely within 1 hour"

Could you run `pstat -t' to see what's going on when it stalls? This
nifty tool just gives some random statistics on TTYs. Very useful to see
what's going on. Where data is stuck, etc. etc.
