: I have specified an interface for input devices as suggested.
: I thing it is pretty nice, and it'll make eisier the port
: of MicroWindows to others RTOS.

A comment on the kbd interface: in addition to the keycode
member, we should also have a scancode member. Some applications
want to see the kbd in scan code mode, others want to see the
keystroke. There should also be a way to put the RTEMS
kbd driver to and from scancode/ascii mode, also.
With PC keyboards, some applications need to know whether
the keypad arrow key or just the arrow key was pressed. The
scan codes are the same, just a different prefix byte from the
kbd controller. So there should be a bit set for that too; I guess
that can go into the modifiers member.
Regards,
Greg
