Parity
[ None ]
[Even]
[Odd]
[Mark]
[Space]
A parity bit can be
sent with the data
bits to detect some
transmission
errors. Even: parity
bit is 0 if the num of
1's in the data bits
is even. Odd: parity
bit is 0 if num of 1's
in the data bits is
odd. Mark: parity
bit is always 1.
Space: Parity bit is
always 0. Mark and
Space Parity do not
allow for error
detection.
Stop Bits
[ 1 ]
[2]
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
[ None ]
[Hardware
RTS/CTS]
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.
