Feature Description Options
Terminal Type
Emulation: ANSI: Extended ASCII char set. VT100: ASCII char set. VT100+:
Extends VT100 to support color, function keys, etc. VT-UTF8: Uses UTF8
encoding to map Unicode chars onto 1 or more bytes.
VT100, VT100+, VT-UTF8,

Bits per second
Select Serial port transmission speed. The speed must be matched on other
side. Long or noisy lines may require lower speeds. 9600, 19200, 38400,57600,

Parity
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
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
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.
