“This does not work” is not a very useful statement.

If you want to run the console on FreeBSD 13 or older at 115200 bps, you
will have to add `comconsole_speed="115200"` to /boot/loader.conf and
`-S115200` to /boot.config and reboot.  On FreeBSD 14 and newer, it is
already the default and you shouldn't have to change anything.  If it's
still not working, I would suggest hooking up an oscilloscope to the
level shifter to check that it's working properly.
