Description
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 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 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. Software flow control uses start/stop ASCII chars, which slows
down the data flow and can be problematic if binary data is being sent.
On this mode enabled only text will be send. This is to capture Terminal
data.
