Thanks, Eric.  I have a couple flavors of 2x20 VFD Pole Displays.  One
is a deluxe model and supports one line of scrolling text (you prefix
the string with ^E, IIRC, and the display itself shifts the
characters).

Do you have a pointer to the AEDEX protocol somewhere, or is it so
simple that it's documented in the comments in the driver?

The ones I have contain TTL serial modules (typically at 4800 bps or
9600 bps) and a simple resistor/diode level shifter (plus a 7805) on a
daughter card.  All of mine have DIN-6 connectors.  Somewhere I have a
commercial DIN-6 to DB25 + 2.5mm power jack, but it's pretty easy to
trace out the leads and manufacture a replacement adapter.  What I
should _really_ do is to modify the pole or the base to have a 2.5mm
jack for a power adapter, plus an RJ45 for Cisco-compatible serial (I
always save old Cisco cables and adapters from the trash when they
pitch out "install kits" at work).

Thanks again for doing this.  I'll see about hooking up one of my
displays and making any necessary changes.
