A parity bit can be
sent with the data
bits to detect some
transmission
errors. Even: par-
ity bit is 0 if the
[None]
num of 1's in the
[Even]
data bits is even.
Parity [Odd] Odd: parity bit is 0
if num of 1's in the
[Mark]
data bits is odd.
[Space]
Mark: parity bit is
always 1. Space:
Parity bit is always
0. Mark and Space
Parity do not allow
for error detection.
Stop bits indicate
the end of a serial
data packet. (A
start bit indicates
the beginning). The
[1]
Stop Bits standard setting is
[2]
1 stop bit. Commu-
nication with slow
devices may
require more than
1 stop bit.

Flow control can
prevent data loss
from buffer over-
flow. When send-
ing data, if the
receiving buffers
are full, a 'stop' sig-
nal 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 con-
trol uses two wires
to send start/stop
signals.
