Direct console driver, version 0.10, MAR 31 1996

init_console() should be called absolutely first in init. Console output
will _not_ work at all if it is not initialized. It's more likely to crash
the whole thing.

The vt52 emulation is implemented, and seems to work. There are some
additions to the vt52 standard:

   o 'ESC P f' inserts a line on cursor
   o 'ESC P d' deletes the current line and scrolls the bottom up.
   o 'ESC Q n' Sets/clears display attributes. n is numeric + ' '.

	* 0 resets the attributes to default
	* 1 bold ( ie. bright ) on
	* 2 blink on

R: This looks like the sort of emulation that a usermode helper could
   build on to implement vt100 emulation. What vt100 functions are not
   available in vt52, and how can they be logically added?

Done some testing on EGA, too. It worked just as well as on my VGA.

Should cli/sti pairs be in each function needing to be atomic or will the
kernel be completely atomic?

A: Probably a good idea because printk() may come from anywhere if its a
   kernel fault/panic etc.

I see. But you seemed to have removed my asms from the previous rel. How?

How about writing some doc on the vfs functions so that the driver
file_operations could be done?

A: They are the same as the Linux ones. They dont actually apply to the
   console since its a tty driver, but we don't yet have the tty layer.

Now did some major changes to new_key.c, now it even works (almost) right.
key_pressed will be removed soon, and the keyboard input is to be done via
GetQueue(), which returns the translated char, or -1 if there's none
available.

Now shift keys invert the capslock state, so a 'A' when in capslock mode
will appear 'a' if a shift key is pressed.

Added translation table for capslock. Still we need loadable keymaps.

A: Prefer compilable...

Ok, guess it will be smaller.

Now the AT keyboard separate arrow keys are translated to ESC[ABCD] like
in vt52. Don't waste your time trying to test this under dosemu, it does
something completely obscure in case of the arrow keys! It seemed to give
something like 0x98 for the up arrow key, when the right scancode if 0xE0
0x48.
