❔ How to resolve System.UnauthorizedAccessException when a serial port is open but already in use
Thanks for your reply 🙏 .
My difficulties is about the user that must choose the serial port from a list of all available ports before the software start and sometimes choose a port that is already in use by other software.
I think that I need a some check of that port before my program start but isOpen is not enough.
