Port numbers shown here are assigned by your browser and may not match your system's COM port numbers. To identify which port is which, open Device Manager (Windows) or check ls /dev/ttyUSB* (Linux). For dual-port radios like the FTDX10, the Enhanced port is for CAT control and the Standard port is for audio/digital modes.
