On the 2nd part the issue was that the host software changed baud rates several times in a second, or so, where it would try one baud rate see if anyone responds, if not, it would try different one… Until something responds.
With this I was having some issues where the analyzer would not pickup the data at the new baud rate, even when there were gaps between their logical packets. I will try to capture this again, but may be slightly fickle to get again.
0th issue is when you are doing terminal output with Serial, and the output stream is using \r characters to terminate lines, the terminal just keeps going back to start of row overwriting the data.
Would be good to be able to choose what your line termination is. for the terminal output
