Write a device driver that runs at Ring 0

Use the appropriate Win32 level 4 API call.

:    (c) light up a dot using active x

Never tried that.

:    (d) light up a dot using direct x

Use the DirectDraw interface API.

Use the Console API.

: pixels, serial, parallel) is quite troublesome.

I'm not sure what you mean by reliable ? You mean without interference
from the sheduler ?

You mean AdaGraph isn't realtime ? <g&d>
