I've worked on those in the past... pretty simple, really, but I
_have_ found two command-set variants... one has a single-character
command prefix (^E, IIRC), that lets you give a string up to so many
letters (40? 45?) that the pole display will scroll across the bottom
line without any further intervention of the host CPU... presumably,
one would use this for scrolling an idle message relevant to the
retailer ("Happy Holidays", "Thanks for shopping at FooMart", etc.)
There may also be a variant command set that encompasses an internal
date/time function - not positive about that. I _am_ sure that I have
seen more than one variety of VFD inside different models. My pole
displays are at home and I am on the road; I'll be able to cite
models, etc., next month.

What I can't remember is what version the driver I did in the past is
for... probably 0.4x.
