I am setting up a kiosk and the ELO Touchsystems touchscreen has a built in CPU. The CPU is using Com Ports 1-21. It is giving me port 22. Does anyone have any experience with using Com Ports in the higher number ranges?
With the configurations below I can get it to say that a thread has started but the communication does not work.
Are you trying to communicate with an Arduino? Which one? It is very hard to help when we are not allowed to see the code that is not working or how the project is wired.
