DEX-100
Bits per second
Selects serial port transmission speed, which must be matched
on the other side, where long or noisy lines may require lower
speeds.
Data Bits
Number of data bits
Parity
Parity bit can be sent with data bits to detect transmission
errors, where
Even: parity bit is 0 if the number of 1's in the data bits is even
Odd: parity bit is 0 if number 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, and can
be used as an additional data bit.
Stop Bits
Indicate the end of a serial data packet (a start bit indicates the
beginning), with standard setting 1 stop bit, and communication
with slow devices may require more than 1 stop bit.
Flow Control
Can prevent data loss from buffer overflow, where, when send-
ing data, if the receiving buffers are full, a 'stop' signal can be
sent to stop the data flow, and once 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.
