When a NCS has to restart it is usually not the fault of the software, but of the NC's computer, the online connection of said computer, or the ever present ISP saving money.
I know a lotof the NCs, heck I am one myself. I'm pretty lucky that I live in a high density area, with reliable communications. That is something that a lot of control stations do not have access to, instead they are limited to a dial up line, or lousy inforstructure between them and the ISP's base.
I think that I had to restart only once and that was when a DUI tried to kill himself by taking down the telephone pole, he didn't but the momentary disruption end my bit stream.

Ah I see. I didn't start pulling the software apart to see how it worked.
I think the lack of responses is a good answer to my question. Maybe I will work on something down the road.
