
Terminal Type
Emulation: ANSI: Extended ASCII char set. VT100: ASCII char set. VT100Plus:
Extends VT100 to support color, function keys, etc. VT-UTF8: Uses UTF8
encoding to map Unicode chars onto 1 or more bytes.

Bits per second
Selects serial port transmission speed. The speed must be matched on the
other side. Long or noisy lines may require lower speeds.

Data Bits
Data Bits.

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 begin -
ning). 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. Hard -
ware flow control uses two wires to send start/stop signals.

VT-UTF8 Combo Key Support
Enable VT-UTF8 Combination Key Support for ANSI/VT100 terminals.
