Hi All,
So taking the advice given in this thread, I made 2 changes that solved my problem. I took a look over the termination characters "endtest" and decided to keep it the same, but change that way I approach the problem. I know that my ascii data always returns with "\n" at the end, so instead of reading one byte at a time with no terminating character configured, I setup "Configure Serial Port" with termination character enabled to "\r". In my loops, I setup the VISA Read to read 4096 bytes (bigger than need to be) to read line by line instead of byte by byte. Instead of concatenating the string, I am now just searching each line instead. This way, the string search is not slowed down by an ever increasing string. I also switched out string "Match Pattern" for "Search/Split" for faster search.
Thanks for all the suggestions and help to put me in the right direction.
Regards,
Mike
