So, the Alpha port calls the `com' serial ports "ttyCn". I would like
to change the i386 port to do the same (and change the current i386 port
usage of "ttyCn" for Cyclades-Y to "ttyCYnn".
Using "ttyZn" for the Cyclades-Z is a lose because eventually I would
like the i386 port to support Zilog serial chips, where "ttyZn" is a
more natural fit.
We should just bite the bullet and make tty names for the same serial
driver common across ports with better descriptive names, leave some
compat names around for a while, but actually handle longer tty names.
