How to get Keyboard inputs into a kernel?

I am writing my own kernel in c. Now I want to code a Console to interact with the Kernel. It should work like the normal Terminal on Linux. How can I get a input over the Keyboard ? Do I have to use Keyboard specific drivers ?

You need to write a driver in your kernel for the keyboard. Assuming a standard PC, the 8042 keyboard controller is pretty well documented (see http://wiki.osdev.org/%228042%22_PS/2_Controller for example). You'll also need to write a driver for the display, and again assuming VGA it is pretty well documented (see http://wiki.osdev.org/VGA_Hardware). Then you'll have to write all of the terminal stuff that sits in between to connect the two.
