Parity
|
None/
Even/

|
None
|
A parity bit can be sent with the data bits to detect some
transmission errors.
None: No parity bits are sent.
Even: Parity bit is 0 if the number of 1s in the data bits is
even.
Odd: Parity bit is 0 if the number of 1s 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
|
01/02/11
|
1
|
Stop bits indicate the end of a serial data packet. (A start bit
indicates the beginning of a serial data packet.) The standard
setting is 1 stop bit. Communication with slow devices may require
more than 1 stop bit.
|
|
Flow Control
|
None/
Hardware/
RTS/
CTS
|
None
|
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 restart the flow. Hardware flow control uses
two wires to send start and stop RTS (request to send) and CTS
(clear to send) signals.

addresses are written with hexadecimal digits and colon separators.
For example: 2001:0db0:000:82a1:0000:0000:1234:abcd. IPv6 addresses
are composed of two parts: a 64-bit subnet prefix and a 64-bit host
interface ID. To shorten the IPv6 address, you can (1) omit all
leading zeros, and (2) replace one consecutive group of zeros with a
double colon (::). For example: 2001:db0:0:82a1::1234:abcd
