I explain my question from any figures:
Simplified views of tty processing:
Scene 1: (Serial terminal)

| Kernel space

tty driver

Scene 2: (PC console)

Scene 3: (PC keyboard + Serial Display: whithout VGA device)
User Program

PC keyboard Serial Display (Text Display)
My question is the next:
What driver can I use to manage Scene 3?
I can run /sbin/login program over Serial Display
(using serial-console kernel support), but I can not
use the PC keyboard, because kernel thinks that we
are on Scene 1, so input must be from serial line and
I need input from PC keyboard.
Best regards. Javi Roman.
