BIOS Advanced Menu Serial Port Console Redirection Options
The following table describes the BIOS Advanced Menu serial port console redirection options.
Setup Options | Options | Defaults | Description |
---|---|---|---|
EMS Console Redirection |
Disabled/Enabled |
Disabled |
Use this option to enable or disable console redirection for Windows Emergency Management Service (EMS) administration. |
Console Redirection |
Disabled/Enabled |
Enabled |
Use this option to enable or disable console redirection. |
Terminal Type |
VT100/VT100+/VT-UTF8/ANSI |
VT100+ |
Select the emulation for the terminal:
|
Bits per Second |
9600 19200 38400 57600 115200 |
9600 |
Select the serial port transmission speed. The speed must be matched on the connecting serial device. Long or noisy lines require lower speeds. |
Data Bits |
7/8 |
8 |
Select the data bits. |
Parity |
None/Even/Odd/Mark/Space |
None |
A parity bit can be sent with the data bits to detect some transmission errors.
Mark and Space parity do not allow for error detection. They can be used as an additional data bit. |
Stop Bits |
1/2 |
1 |
Stop bits indicate the end of a serial data packet. (A start bit indicates the beginning of a serial data packet.) The standard setting is 1 stop bit. Communication with slow devices may require more than 1 stop bit. |
Flow Control |
None, Hardware RTS/CTS, Software Xon/Xoff |
None |
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 restart the flow. Hardware flow control uses two wires to send start/stop signals. |
