Some DEC terminals, like the VT340, have a "sixel graphics" mode.  Yes,
six bits in a row IS too easy.  It's six bits stacked VERTICALLY, so 
instead of using the sixel commands to send out individual scanlines,
you send out six rows at a time, column by column.

I have no idea if Xerox uses the same convention, though.
