Ok thnx i will try this. I should note that don't have the exact
handyboard. Ours is called the botboard but it's based on the same mcu
and works fine with pcbug11.

Well we're aiming for a real environment and therefore i think it
would be elegant to have incorporate it. Ofcourse I thought the same:
why redo somebody's work... So I emailed Vladim to see if I could get
his sourcecode and do some cutting and pasting, but I didn't get a
response so I thought that maybe he's not MIT anymore...

My board doesn't have an LCD:-) Besided we want to use the same
debugging interface for simulated and remote debugging.

I'm a big fan of open source so yeah if I call the shots it will be.
But our mentor wanted us to develop it for use here at the uni.. We
haven't really discussed it yet but you have my vote:-)
Byebye!
