13-RC2 Serial Console not accepting Input

[Dean E. Weimer]

I upgraded a system from 12.2 to 13-RC2 running on an PC Engines Alix 
APU1D4 system board. It boots and works fine, however despite console 
output displaying fine, it will not accept any keyboard input.

I have the following in my /boot/loader.conf

# Enable Serial Console
console="comconsole"
comconsole_speed="115200"
boot_serial="YES"

Am I missing something else that has changed requiring a new option to 
be set for serial consoles?
