This is actually the point that I have attempted to figure out until now. We see an example for server side for the registration of IRQ object.
However there is no such a thing on the client side. If there is, I couldn’t find it which means that I have to keep reading the code.
The simple question is actually how we can listen IRQ request on the cline side, especially in which source code should I search the response?

I have seen the loop code and its working mechanism as well as have noticed how to manipulate it. Honestly, the code is in a considerable manner huge and it is quite easy to muddle the whole thing. Probably, I would change this server loop according to my conditions. 

Thank you so much again.
