Hi,

I don't need to stick to interrupts; I just thought this would be a good idea....

The thing is, I don't know the right (or best) "tool" to use and I appreciate your help and comments to take the correct path for my project

"Ring buffer" is new to me so I'll first have to spend some hours of reading and searching to get more info. My monitor prototype is already in the field and every immediate improvement, the one I may have the skills to make immediately, is the always the best.

So, because of my lack of knowledge (but it is getting better every day), these are the tools I will rely on for now:

Having a routine checking the received message list every 5 seconds or so will allow me to start to improve the reliability of my monitor asap.

Richard is right: I'm mixing up things and tracking incoming serial data is actually not that crucial. For any reason, I was focusing on the wrong target....
