Thanks for the reply. Hopefully I can get a clue and have this up and
running in a sec.
Try running the LCDd server with the parameters -f 1 -r5 -s0

$LCDd -f1 -r5 -s0

Not until now, I did not know whether it was 4-bit, 8-bit, etc. Thanks for
pointing that out to me.
Did you talk to your vendor about it ?
I did, but they were slow to reply. I will try to email them again and see
if they can give me some clues as well. I must say, this is the first time I
have worked with any lcd, and I am quite lost.
Next possibility for failure: the "Port" setting the [hd44780] section of

I have the lcd connected via Centronics adapter to the parallel port. I have
only one parallel port on my computer and one hd44780 screen connected.
While reading another howto, it's settings suggested this was the correct
setting to use, so that's what I went with. I hope it is correct, but I am
not entirely sure.
Thanks all,
Joey French
