The simpleUsbBackchannel example receives data over the backchannel UART and sends it back to the host PC over USB (see Figure 31). By default, the USB connection uses a CDC interface, which results in a virtual COM port on the host. Thus both sides of the communication loop terminate in virtual COM ports on the host. Through these COM ports, two instances of a terminal application can exchange data.
