Does this mean one can drive the BIOS setup screens, AS WELL AS all
add-on card BIOS setup screens, and then see the kernel printfs and talk
to a single user shell, all from a single serial port?

That's just a feature of the FreeBSD console driver though, isn't it?

(That you can send a scroll-lock keypress event is cool and all, but
what about over a serial console?  That's all I care about.)

Anyway I don't think NetBSD's wscons(4) supports scroll-back of console
messages (yet?)....  at least not in the netbsd-3 branch, and if so then
it's not documented properly yet.
