Plot serial data to chart

[Ray.R]

I would be surprised that the code you posted would have worked.  Why did you not build onto the example I provided?  (why do I bother creating proper examples???)

And adding another While Loop inside a Case Structure spells t-r-o-u-b-l-e.  You claim that it works? 

I'm curious...  Can you post that working code?

I altered my old code and it is actually very similar to your example. 

Before I only had one while loop and now I have two.

Just like in your example, I added the loop around the inner case structure.
