Selects serial port transmission speed. The speed must be matched on the other side.
Long or noisy lines may require lower speeds.
Flow Control EMS
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.
Data Bits EMS
Data Bits
Parity EMS
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.
They can be used as an additional data bit.
Stop Bits EMS
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.
