CONS(4) Device Drivers Manual (hp300) CONS(4)

cons
HP300 console interface

This release supports a “virtual” console device used for kernel printf messages and accessed in user mode via /dev/console. It is virtual in the sense that it is attached to a hardware interface at boot time. Currently the choices are limited to: a bit-mapped display acting as an internal terminal emulator “ITE”, the builtin serial interface com(4), or a null(4) console in that order.

/dev/console
 

com(4), tty(4), reboot(8)

You should be able to specify potential console devices at config(1) time.
