However,
if the LCD Display Panel supports touch screen,

connected to COM 3 therefore a default address has already been
assigned to this port. Make sure COM 3 is not attached with a
serial device.

This is used to select an I/O address for the onboard serial port 4.
Serial Port 1 Use IRQ, Serial Port 2 Use IRQ, Serial Port 3 Use IRQ
