Unforch, at least from this linux keyboard, there are significant keycode 
translation problems when running minicom against a shell on the coco3's /t2 
device, so I have to actually goto the coco's keyboard to run any app that 
manipulates the screen content or cursor positions, such as ed(vi in camo) or 
ded.  Multiview would be completely out of the question of course given those 
limits.
