Flow Control
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.
