Maybe I'm just daft, but I don't see it in mythsetup or the frontend
setup?  I didn't even see the word LCD mentioned in the mythtv.org
documentation.  Think you can point it out to me?  Thanks.

My VFD is a Parallel with a serial controller on top of it.
Unfortunately, it's not listed under any of the drivers for LCD proc,
which is why I'm winging it.

I think you may be right on the driver part, but as for the RTFM comment,
the HD44780 driver also supports the Pic-an-LCD interface which is very
similar to my setup, and distributed by the same people who do my VFD.  If
you RTFM, you learn that you use the "Device=" line to set the driver to a
serial port, as I stated in my previous post.

I've since read that the Matrix Orbital LCD's use an echo interface to the
serial port, so I'll be trying it shortly.

Thanks,
Ben
