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?
