This code snippet shows how to find out the available comms ports on your computer.:

    static void listPorts()
    {
        Enumeration portEnum = CommPortIdentifier.getPortIdentifiers();
        while ( portEnum.hasMoreElements() ) 
        {
            CommPortIdentifier portIdentifier = (CommPortIdentifier) portEnum.nextElement();
            System.out.println(portIdentifier.getName()   " - "   getPortTypeName(portIdentifier.getPortType()) );
        }        
    }
    
    static String getPortTypeName ( int portType )
    {
        switch ( portType )
        {
            case CommPortIdentifier.PORT_I2C:
                return "I2C";
            case CommPortIdentifier.PORT_PARALLEL:
                return "Parallel";
            case CommPortIdentifier.PORT_RAW:
                return "Raw";
            case CommPortIdentifier.PORT_RS485:
                return "RS485";
            case CommPortIdentifier.PORT_SERIAL:
                return "Serial";
            default:
                return "unknown type";
        }
    }
