This is a cheap serial LCD I picked up at an MIT Flea. here's a little info: http://www.altechelectronics.biz/16-x-4 ... -1007.html . It's actually two discrete 2x16 LCDs connected with a microcontroller. There was a bit of helpful instructions included, but it was missing a lot of necessary data to make it actually useful. I got it working with LCD Smartie's testdriver with the following config (watch out for excess spaces, which i put in for formatting linebreaks in phpbb):
Startup parameters: COM1,4800,8,O,1
testdriver.ini:

Yes, that's a real mess for line2 and line4. That's because as far as I can discover, the only way to get to the second line on these babies is to go to position 1 and then move forward or back 25 characters - and each cursor movement requires 2 signal codes (one to tell it which display to use, the other for the actual command).
It uses DV-16210 panels, which seem identical to these Novateks in practice (and these docs are better): http://www.pacificdisplay.com/ics_app%2 ... NT7603.pdf
Weird notes: Besides what they mention in the above documents, a ctrl-q needs to precede control signals sent to the top display, and ctrl-u for all bottom display. ctrl-r sets the top to writing mode, ctrl-v sets the bottom to writing mode.
There's not much identifying info on this board: the chip says 16215-1, and the PCB says Data Vision P345A, but I can't really find much else.
If anyone else has experience with this please comment - and let me know if anyone finds this useful.
