Hi Richard, Reading the project homepage I read the following statement: "Modular design allowing painless addition of new transports and clock servos.".
This is an aspect really interesting for me, because in my environment I haven't true linux interfaces and the serial line discussed above. Is there an example of "new transport" implementation using your API? My idea is to directly hack transport.c/.h files adding a new entry inside the create switch. Is it the correct way? Or do you have any other suggestions?
