ETX-OH / BIOS Operation
COM0/COM1 Console Redirection Settings
Feature Options Description
Terminal Type VT100
VT100+
VT_UTF8
ANSI
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
ANSI: Extended ASCII char set.
Bits per second 9600
19200
38400
57600
115200
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 Data Bits
Parity None
Even
Odd
Mark
Space
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.
Stop Bits 1
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
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 'start' signal can be sent to re-
start the flow. Hardware flow control uses two wires to
send start/stop signals
