Dennis thanks for your response. I am obtaining an Eeprom reader that will connect to my COMM port. This device itself will connect to an external Eeprom to read the data. I need to know if there are any functions, components, etc that I can use to read said Eeprom. As for the COMM port, there are many components out there to read data too and from. I just need to at least figure out how to get the data from the Eeprom to the COMM port. Any ideas, examples, or websites you know of, feel free to fill me in.
