I subscribed to this mailing list yesterday, requested a bunch of ole
emails, read them, and I think I'm more confused than when I started.

I have an Optrex DMC40457 4x40 LCD. This is one of those LCDs that has
two HD44780 chips on it, so it has two control lines and acts like 2 2x40
screens. It has 16 pins on onw side (only 15 are used) and two power pins
on the other (I'm not sure which is pos or ground).

I read that people were hooking their LCDs up to the printer port or the
serial port. Is this right? How do I know which one to use, and where to
I go to learn what pins on my LCD go to what pins on the port I need to

Has anyone tried this LCD? It was given to me by someone who had it given
to them by someone that told them it would work with LCDproc :)

Anyone gotten LCDproc running on FreeBSD?

Thanks a lot,
