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.
