Flow control can prevent data loss from buffer overflow. When sending data, if the
receiving buffers are full, a 'stop' signal can be sent to stop the data flow. Once the
buffers are empty, a 'start' signal can be sent to re-start the flow. Hardware flow control
uses two wires to send start/stop signals.
