Data Bits
Parity
A parity bit can be sent with the data bits to detect some transmission errors.
Even: parity bit is 0 if the number of 1's in the data bits is even
Odd: parity bit is 0 if number of 1's in the data bits is odd.
Mark: parity bit is always 1.
Space: Parity bit is always 0.
Note: Mark and Space Parity do not allow for error detection.
Stop Bits
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.
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.
