If the installation did not go well, an exclamation mark appears on the « USB <> Serial » line or on the
« USB serial port (COMX) » line and indicates a malfunctioning of the interface.
It is important that you remember to which USB port the cable is connected.
Always connect the appliance to the same port in order to avoid reinstalling
the driver or changing the COM port number.
