Serial console needed

[Dima Veselov <kab00m_(_at_)_lich_(_dot_)_phys_(_dot_)_spbu_(_dot_)_ru>]

Hi there!

How I can use serial console only on my OpenBSD-2.9 i386 machine?

The problem is: if computer wouldn't have any video device needed for a
console it hangs during startup. I have no free expansion slots there. All
slots are busy with NICs :-)

I tried to compile kernel without wscons, but not succeded.

Is serial console not a dream?

Thanks for answer,
                  Dima
