You can spawn a login prompt on com0 through /etc/ttys and avoid changing

That’s the best dual support you’ll get.

i'm afraid, this will not help me to fix filesystem errors, which i get time
to time because of power outage.
How would two consoles help you fix FS errors after a reboot
(as opposed to having one console after a reboot)?

very easy :) i won't have to go to work on the weekend, because i have another machine near, which i've could use to connect to console.

Unfortunately, i do not have any kvm or ipmi on my OpenBSD machine, and cannot afford it.

it's the main reason i wanted second console.
It is way easier to help
if you make you main reason clear
at the very start of your post.

I already seen those posts about patching rc to make fsck be more automatically, i think this is terrible solution.

So, i thought, maybe there is another way.

You can configure a serial console in boot.conf, and switch back to
the default local console by holding the Ctrl during bootup to skip
loading the conf file (on i386 & amd64 at least, not sure about other
arches).  From boot(8):

   boot.conf processing can be skipped, and the automatic boot
cancelled, by holding down either Control key as boot starts.
You've got to be very lucky with timing on some machines.
