Thanks for the info.
I have checked the electronics on the back of my LCD and it turns out
that I have a lightly different model that cant be modded for TTL.
So that leaves me with 2 options - the serial mod with an RS232 level
converter or using a micro-controller.
Which of these options is the easiest? I am guessing the serial mod as
I can just use standard RS232 without worrying about collisions etc.
Is it pretty straightforward to send/receive commands via the modded
serial port? Are there any examples that anybody has? I just want to
find out how involved it is before I go and find my soldering iron!
