The Serial component has the following slots:
- Status: indicates the current status of the component. If the component works properly, its status is OK; the component's status becomes Disabled if its Enabled slot has been set to false.
- Available information: Disabled, OK.
- Enabled: change of the slot's value enables or disables the component.
