However, you want to connect to your modem via the USB-serial adapter, which is, in your case, '/dev/cuaU0' (after plugging the device into your PC). There is no logic which decides which serial device will be used, '/dev/cuau0' and '/dev/cuaU0' are two different devices, and you need to connect to the one you want to use. For example, connecting another USB-serial adapter will generate a third device, '/dev/cuaU1'. You can also find a description of the naming in the docs: https://docs.freebsd.org/en/books/handbook/serialcomms/ -- Souji Thenria
