Intensity, brightness #4

Closed larsbrinkhoff closed 3 years ago

larsbrinkhoff commented 3 years ago

Characters can have three intensity levels: dim, normal, and bright.

Overall display brightness is controlled in the SETUP using ↑ and ↓.

larsbrinkhoff commented 3 years ago

Overall brightness ranges from 31 (darkest) to 0 (brightest). I implemented this, but I don't know how dark 31 is.

A VT100 without AVO does not have the character attribute bits for dim/bright.

Leave intensity for a later update supporting AVO.
