FYI,

I do not use serial communication. All my hardware communication is through a c++ dll.

I will have to do some more research, but from what I seen Delphi increments each version with mainly improvements, and something written in 1995, could very easily be converted and compiled in 2014. From what I understand there was never a version that completely broke everything as in vb6-.net. Correct me if I am wrong.
