Make sure that the PORT variable in the Makefile is set to the name of the device’s virtual serial port. In Windows, {{fname|\\\\.\\USBSER000}} should work if the A-Star is the only USB device connected that is using the usbser.sys driver, but you can change it to be the actual name of the COM port (e.g. {{fname|COM13}}).
