RE: [Geekos-devel] user mode works again

[Harry G. <hg...@ya...>]

So far the OS seems pretty neat. I have gotten it to run on my labtap =
(more details on forums on sourceforge) and I would like to extend some =
of the features a little. I was messing around with the keyboard driver =
and I was able to have it delete characters already on the screen. After =
I finished that, I noticed that the driver would be a bad place to get =
the backspace to do its thing. Think that the Read_line function in =
libuser.c (i think that is where it is at needs to be changed to =
accomodate backspace functionality). I wanted to make a small little =
command line program for it with some built in built in commands. Do do =
that, the libuser.c needs to be fixed. I don't think it would be that =
hard to take the code that I put in my copy of keyboard.c and move it =
into libuser.c. Maybe while I'm at it, I could add some new functions to =
it too.
