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.
