Thanks! So I did "sudo cat /dev/ttyS4" in the terminal. After 10 seconds, the cursor blinking stopped, then I touched the screen with the pen, it started giving output non-stop. Like the output never stopped, I had to close the terminal. Is this a good sign that my touch screen is attached to serial port 4? Regards, RG.
