redirection can also be enabled, and the port address can be specified. This option is set to Auto by default.
Serial Port Enables you to set the port address for serial device. This field sets the serial port address to either COM1 or

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.
