Yeah, my idea is the following: provide a getchar and a putchar ioctl, that
can access random postions on screen buffer (see my other post). Each ioctl
should return the letter in the position, as well as its attributes. Why?
wsmoused will need to change their color to make the cursor appere. Well,
I don't know how other archs work, but I guess they are still using
character+attributes. So, returning/setting a simple structure with both
fields would be the main idea.

Then, wsmoused is the program that will control mouse movement, selections,
and pastes. Kernel changes will be minimun, and can also be made optional.

So, what do you think?

Thanks
