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

Data Bits
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.
