Selects serial port transmission speed.
The speed must be matched on the
other side. Long or noisy lines may
require lower speeds.

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 indicates 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 buf-
fers 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 sig-
nals.
