There's far to much wrong with that statement to go into, starting with the
docs talking about DCD, not DTR, and ending with current OSX systems not
creating a cua device at all, so if freebsd.c is being used on them, then
it won't work with serial devices at all.

But none of that matters. What matters is that BSD users have been using
/dev/tty* files to talk to serial devices that don't make phone calls for
over four decades, the authors of serial device drivers expect and support
that behavior, and it works. Forcing them to use a cua device is a
violation of POLA.
