Stop Bits [1]
Stop bits indicate the end of a serial data packet. (A start bit indicates the
beginning.) The standard setting is 1 stop bit. Communication with slow
devices may require more than 1 stop bit. Conguration options: [1] [2]
Flow Control [None]
Flow control can prevent data loss from buffer overow. When sending data,
if the receiving buffers are full, a “stop” signal can be sent to stop the data
ow. Once the buffers are empty, a “start” signal can be sent to re-start the
ow. Hardware ow control uses two wires to send start/stop signals.
