Serial Communication details
About this task
The
Serial Communication
screen details are explained as follows:
Option
Description
Serial
Communication
Enables you to select serial communication devices (Serial Device 1 and Serial Device 2) in BIOS. BIOS console
redirection can also be enabled, and the port address can be specified. This option is set to
Auto
by default.
Serial Port
Address
Enables you to set the port address for serial device. This field sets the serial port address to either
COM1
or
COM2
(COM1=0x3F8, COM2=0x2F8). This option is set to
Serial Device1=COM2 or Serial Device 2=COM1
by default.
NOTE:
You can use only Serial Device 2 for the Serial Over LAN (SOL) feature. To use console
redirection by SOL, configure the same port address for console redirection and the serial device.
NOTE:
Every time the system boots, the BIOS syncs the serial MUX setting saved in iDRAC. The
serial MUX setting can independently be changed in iDRAC. Loading the BIOS default settings
from within the BIOS setup utility may not always revert the serial MUX setting to the default
setting of Serial Device 1.
External Serial
Connector
Enables you to associate the External Serial Connector to
Serial Device 1
,
Serial Device 2
, or the
Remote
Access Device
by using this option. This option is set to
Serial Device 1
by default.
NOTE:
Only Serial Device 2 can be used for Serial Over LAN (SOL). To use console redirection by
SOL, configure the same port address for console redirection and the serial device.
NOTE:
Every time the system boots, the BIOS syncs the serial MUX setting saved in iDRAC. The
serial MUX setting can independently be changed in iDRAC. Loading the BIOS default settings
from within the BIOS setup utility may not always revert this setting to the default setting of
Serial Device 1.
Failsafe Baud Rate
Specifies the failsafe baud rate for console redirection. The BIOS attempts to determine the baud rate
automatically. This failsafe baud rate is used only if the attempt fails, and the value must not be changed. This
option is set to
115200
by default.
Remote Terminal
Type
Enables you to set the remote console terminal type. This option is set to
VT100/VT220
by default.
Redirection After
Boot
Enables or disables the BIOS console redirection when the operating system is loaded. This option is set to
Enabled
by default.
