If you want to run the console on FreeBSD 13 or older at 115200 bps, you will have to add `comconsole_speed=3D"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. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@FreeBSD.org
