How is it possible to draw full-screen photo images on a VT320 & 420 then?
Obviously they're 1-bit color and it takes a few minutes but it has been done.
Must have some sort of graphics capability. I recall reading in the manuals that 
there was the sixel capability enabled with a particular escape sequence.

The same photo image would appear in 4-bit color on the VT340. Takes longer to 

Could do the same on a plasma touch terminal (forgot the name) emulating 
VT100/102, as well.
