Yes.

The functions are designed to act as helpers for old devices. In fact
we can actually probably abolish tty_termios_baud_rate at this point as
I don't think there is much if anything left which blows up fed a non
Bxxx table entry.

I will have a look at that in fact see what it involves at this point.
