Item Option Description
Terminal Type
VT100
VT100+ [Default]
VT-UTF8
ANSI
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.
Bits per second
9600
19200
38400
57600
115200 [Default]
Selects serial port transmission speed. The
speed must be matched on the other side. Long
or noisy lines may require lower speeds.
Data Bits
7
8 [Default]
Data Bits.
Parity
None [Default]
Even
Odd
Mark
Space
A parity bit can be sent with the data bits to
detect some transmission errors. Ever: 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.
Stop Bits
1 [Default]
2
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
None [Default]
Hardware RTS/CTS
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
