Thanks for the fix! But it looks to be only partial. When I connect to
the serial console via either cu or screen, I don't get corrupted text,
but no keypresses are registered. Hitting enter at the login prompt does
absolutely nothing. I'm at the latest commit of hardened/current/master
on HardenedBSD for both the RPI3 and my laptop.

I'm using this serial cable from Adafruit:

Thanks,
