Bits per second
[9600], [19200],
[38400], [57600],
[115200]
Select serial port transmission speed. The speed must be
matched on the other side. Long or noisy lines may require
lower speeds.
Data Bits
[7], [8]
Select 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 number of 1's in the data bits is even.
Odd: Parity bit is 0 if the number of 1's in the data bits is odd.
Mark: Parity bit is always 1.
Space: Parity bit is always 0.
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.
