Thanks Peter, I get your meaning, and I think your suggestion
is right, not only because your reason, but also I find
this patch change the user interface behavior silently,
it will cause data lost or others' undesired behavior if
TCXONC restart tty but another side is not ready, it is bad.

I will send the V2.

Thanks.
