I've noticed the third-party software modem drivers in ports have this
problem. I looked at what it would take if we were to rewrite them as
uart(4) attachments and was pleasantly surprised to find it'd eliminate
the reckless forking of sio(4).

However, eliminating the naming inconsistency here can only be a good
thing; if uart(4) can be kept in sync with these tty changes so much
the better.
