alright, pt 2 :)
I got a parallel port monitor set up, and I've got some really nice graphs of the command structure... Or something like that :/
Problem is, the parallel port seems to be interfering with the operation of the LCD. It's really odd; It's registering state changes on all lines (high/low), so I know it's not holding the pins high or low... but if it's hooked up the LCD stops working (no display at all...) So... Maybe the port is 'slowing' state changes? Or... I don't know. Any ideas, suggestions?
