+===== Serial Line CAN =====
+Some USB to CAN adapters may run a firmware that presents as a CDC-ACM serial port, e.g. CANable devices. **slcand** can talk to the devices over the virtual serial port and create a standard SocketCAN device, at which point you can continue the same as with a native SocketCAN adapter.

+The -s arguments sets the CAN bus speed:
