I don't know about the adm3a, but the tvi91x series has one visual attribute
that isn't an imbedded on the screen, that of dim.  I hate the magic cookie
glitches a lot of terminals have and all the termcaps I've designed for the
tvi's (and other look-a-likes) use dim for both standout and underline.
