FreeBSD does not support 100% dual-console configuration under all
stages of use; that is to say, single-user prompts will be output to
either VGA or serial console, but not both.

Some additional tips:

Not required if you use -S115200 in /boot.config.

Not needed; see above.

Not needed if -Dh is added to /boot.config (e.g. -S115200 -Dh).  Hope
this helps.
