Papenmeier 2D series.  THe status cells are vertical.  IIRC, most mdels
come with 25 status cells, one cell for a typcail 80x25 screen.
With their driver software, they use that feature mostly to give
an overview of screen contents.  SO if a line is empty, the
cell is empty too.  These status cells have routing keys as well,
for quick goto-line.
