Read from a 7-segment display LCD Answered

Hello everyone.
Suppose you have some device with a numeric LCD display with some 7-segment digits (i.e. a digital scale), and you want to hack it in order to read out electronically (for example with an rs232 connection), while preserving functionality of the thing.

How you would do that?

You don't. The display take input from an outside source and displays it. It has no way of sending a signal out of what is on the display. What are you trying to accomplish?
