Topic: No Serial Port Options (Read 796 times) previous topic - next topic


I just installed the software and selected my board (Uno), but it won't let me select a serial port. It's just grayed out...I'm running this on my laptop with Windows 8. Anybody have any suggestions what might be wrong? Is it possible I don't have any COM ports? If so, does anyone know how to get around this?


Is the Uno & cable plugged in?
