Hi. I'm using one of the aforementioned displays to replace an hd 44780 driven display. In the specs it says it can be either serial or parallel.. Out of the box which mode is it in and to get it to work to replace a 44780 display, what must I do. Currently it displays a few characters and locks the operating system of the machine up. When unplugged, the machine can operate (indicators and such will function). Thanks for any help!
