I am asking this here since you have probably met the problem. I have developped an embedded system that has a serial link (RS232) as user interface. So far we used a terminal to communicate but I now need to develop a gui application for windows 7.
I have tried doing that with Excel with a commercial active X but I get an "acces denied" error when I open the port.
I have also tried python with serial python but there are installation issues.
What would you suggest as a solution?
