If this property is set to True, ActiveX control will open serial port using the condition specified by CommPort Property and BaudRate Property. To know port has been opened successfully or not, check Active Property is True or False. If this property is set to False, then port will be closed. If you forget to close serial port when you terminate application, don’t worry, ActiveX control automatically close serial port.
