(*) P.S.: i think that a VT100 _with_ AVO interprets the 'basic attribute' as inverse, while one without treats it as _underline_. [/b]
I recall this being one of the (few) differences between running programs on the Rainbow and running them on the VT102 at work (which had the AVO stuff). It mattered only for one silly program I ran back in the day, but I can't recall what that was.
P.S. I'm back. I had to take a couple months off from this project, but I'm back now.
