It will probably be Monday before I can hook up a laptop to the serial
port to try to collect data, but it's not hard.

I put the line:
0:ad(0,a)/boot/loader -D -S38400
into /boot.config and
into /boot/loader.conf.

You probably have /boot/loader.conf, but /boot.config will probably need
to be added.

If you want to be able to log in to the console port, you also need to
enable it in /etc/ttys. (usually ttyd0).
