Headless Install

[Maksym Marchenko]

Hi!

I try to install 4.10 on headless PC(without a monitor and vga output)
So I've used my laptop as a serial console (via null modem cable).
All was wonderfull, but after end of install procedure und reboot,
I see with this terminal (cu -l /dev/cuaa0) all and the date for
the login line. But not the login prompt. So I can't to log in and
do anything.
What have I to do, to log in this headless PC?
Another terminal may be?

Thanks in advance.
