Why would one want such a thing as /dev/cuaXX ? I've had the same problem
recently (modem, xntp-refclock), and found ttyflags(8?), which allows you to
configure /dev/tty0? as a dial-out device at boot time (well
basically). Adding "softcar" to the appropriate lines in /etc/ttys worked
perfectly for me, and this solution is obviously architecture-independent.
