HI  
I am facing this issue with one of the serial instruments  
when I am deploying the flow I am getting the data instantly -\> as seen in timestamp node with injecting after 0.1 secs  
but after that  
whenever I trigger or through the interval it is going from waiting for the state to timeout even when an instrument is giving data.

Recently it is behaving like this any idea or similar issue anyone has reported recently ?

Why not just use the `serial in` node?
