I should say "fixes conditionally". NONE of these programs are going to
work correctly if the serial port is already set to split speed without
also clearing CIBAUD, but there is literally nothing we can do about
that; except perhaps *always* setting CIBAUD to BOTHER (except on Alpha)
and set c_ispeed to 0 on the termios2 kernel interface side instead of
equal to c_ospeed.

Let me ponder that option for a little bit (it just struck me right now;
I had not considered it before), and look to see that the kernel
actually will DTRT in that case.
