FWIW, I do lots of serial consoles.  Biggest issue I have is the
boot.config options.

Personally, the switches to "detect" (-P) and "switch" (-h) don't
always seem to work (for me).

If I have to see anything at the console, not only do I setup
/boot/loader.conf but I will always use -D in /boot.config -- Dual
setup.  It pushes to both COM1 and VGA.

Please try that.
