A while back there was traffic about how to interface the Futaba VFDs from
Info. Unlimited. I lost my copy of the example file...anyone want to email
it to me?
Thanks

Yes I figured out the jumpers were backwards. Working fine at
9600(J1&J2 shorted). Have not tried it on a BSI(at lower bauds) yet.
When I had OUTx=1 after DIRx=1 I would get a glitch character in
position 0 on Reset. Switching around seemed to fix that. Without
the Pause 50 before sending the first data, I would get some
garbage and text starting at the wrong place on power up
occasionaly.
Enjoy,
