Will only work on Linux!
Please, read the package information for SocketCAN first!
The example is configured to use the virtual CAN interface "vcan0". The
SocketCAN package documentation describes
briefly how to bring up such a virtual CAN interface in Linux.
Two sockets are opened in the example: One for sending messages, the other for receiving them.
The SerialPackager blocks are used to add/retrieve data to/from the messages.
