VT100 Emulation: ANSI: Extended ASCII char set. VT100:
VT100+ ASCII char set. VT100+: Extends VT100 to support
VT-UTF8 color, function keys, etc. VT-UTF8: Uses UTF8 encod-
ANSI ing to map Unicode chars onto 1 or more bytes.
9600
19200 Selects serial port transmission speed. The speed must
38400 be matched on the other side. Long or noisy lines may
57600 require lower speeds.

A parity bit can be sent with the data bits to detect some
None transmission errors. Even: parity bit is 0 if the num of 1's
Even in the data bits is even. Odd: parity bit is 0 if num of 1's
Odd in the data bits is odd. Mark: parity bit is always 1.
Mark Space: Parity bit is always 0. Mark and Space Parity do
Space 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
1 start bit indicates the beginning). The standard setting is
2 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
None
'stop' signal can be sent to stop the data flow. Once the
Hardware
buffers are empty, a 'start' signal can be sent to re-start
RTS/CTS
the flow. Hardware flow control uses two wires to send
start/stop signals.
