	Main UART testing example sub-routine First, the user must type 'A' or 'a' character to start Auto baud rate mode. Once Auto baud rate mode completed, print welcome screen, then press any key to have it read in from the terminal and returned back to the terminal. Press ESC to exit Press 'r' to print welcome screen menu again.
