Windows 10 COM port issues plague many users whose computers have been designed without the inclusion of any serial interfaces.

NOTE: If you get cannon open /dev/ttyS4: Permission denied, you may need to add your user to the dialout group.

There are devices, who can't communicate on ports over certain number and 13 is quite high. Try to change it to, say, 3 or 4.
