About COM retention

The USB to serial adapter features COM retention (also known as COM port retention). With COM retention, the COM port settings that are assigned the first time that the adapter is connected to a computer are retained, regardless of the USB port that the adapter cable is connected to. When you disconnect the serial adapter cable and plug it into a different USB port on the same computer, you don’t need to reconfigure the serial port.
