69
Bits Per Second
This feature sets the transmission speed for a serial port used in Console Redirection.
Make sure that the same speed is used in the host computer and the client computer. A
lower transmission speed may be required for long and busy lines. The options are 9600,
19200, 57600, and
115200
(bits per second).
Flow Control
Use this feature to set the flow control for Console Redirection to prevent data loss caused
by buffer overflow. Send a "Stop" signal to stop sending data when the receiving buffer
is full. Send a "Start" signal to start sending data when the receiving buffer is empty. The
options are
None,

A parity bit can be sent along with regular data bits to detect data transmission errors.
Select Even if the parity bit is set to 0, and the number of 1's in data bits is even. Select
Odd if the parity bit is set to 0, and the number of 1's in data bits is odd. Select None if you
do not want to send a parity bit with your data bits in transmission. Select Mark to add a
mark as a parity bit to be sent along with the data bits. Select Space to add a Space as a
parity bit to be sent with your data bits. The options are
None
, Even, Odd, Mark and Space.
Stop Bits
A stop bit indicates the end of a serial data packet. Select 1 Stop Bit for standard serial
data communication. Select 2 Stop Bits if slower devices are used. The options are
1
and 2.
ACPI Settings
