[Paraview] Communicating with a Paraview (GUI) server

[Olumide]

Hi -

I'm aware that Paraview operates/implements a client-server paradigm. 
This suggests that it may be possible for an external (e.g. C++ 
application) to communicate with a running instance of Paraview, by 
sending it commands (e.g. open legacy VTK file) via the port attached to 
the server.

I'd appreciate pointers on how to do this.

Thanks,
