You could probably just create an interface to an existing library that can handle serial like [http://jamod.sourceforge.net/](http://jamod.sourceforge.net/)

Thanks,I just want to know how the example code of OPCUA driver with Modbus TCP Driver to be adapted for one which is not based on TCP IP.  
AbstractNioDriver provides the networking bits and pieces. so | must extend directly from AbstractDriver other than AbstractNioDriver . how can implement the Driver interface to send and receive data?
