Currently I see similar (but hobbyist) projects in the Arduino forum. I never tried real time programming on Win32/64, nor did I use COM port components with Delphi. In the early PC days I did some data acquisition using GW-Basic, later with BCB on Win3. I'd no more try to make my hands dirty with real time programs for Windows, and in detail not with Delphi, be some old reliable (up to D7) or uncomfortable and bloated new (RAD Studio) versions. It's interesting to hear that you still are in business :-) DoDi
