You are right.  -h is the toggle to switch between the internal
(keyboard and video) console and the serial console.  You are also
right that -P is the option you need in your situation.

The man page for loader(8) states that /boot/boot.conf is deprecated.
But it doesn't say /boot.config is obsoleted anywhere.  The man page
for boot(8) describes the usage of /boot/config.

Yes, these names are confusing and that is, AFAIK, exactly the reason
why /boot/boot.conf is deprecated :-)

I am writing up a handbook section for the serial console configuration.
The draft is at:

	http://www.freebsd.org/~yokota/serialconsole.html

I am writing it for the audience exactly like you.  Please have a look
and send me any comments and suggestions.
