I Have a Data Vision P135 LCD display,I just finished wiring it and hooking it up to power, So I got to the point where I get all the power on, like the Backlight, and the character spaces turn black, but can't get any further, I think It is because I dont have ant software to interface with it, I will get photos soon,
Heres a link to my pics, I cant get yahoo to let me remote link, http://f2.pg.photos.yahoo.com/ph/ss_storm@sbcglobal.net/album?.dir=/2c94
Yeah, its showing the test screen. Look for software that runs HD44780 charcter displays, Im guessing 2x20 is yours. Wire it to the parallel port.
