Serial Communication screen

You can use the Serial Communication screen to view the properties of the serial communication port. To view the Serial Communication click System Setup Main Menu → System BIOS → Serial Communication.

Menu Item	Description
Serial Communication	Selects serial communication devices (Serial Device 1 and Serial Device 2)
	in the BIOS. BIOS console redirection can also be enabled and the port
	address can be specified. By default, Serial Communication option is set
	to Auto.
Serial Port Address	Enables you to set the port address for serial devices. By default, the
	Serial Port Address option is set to Serial Device 1=COM2, Serial Device
	2=COM1
	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. Therefore, 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.
External Serial Connector	You can associate the External Serial Connector to Serial Device 1, Serial
	Device 2, or the Remote Access Device using this field.
	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. Therefore, 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	Displays 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. By default,
	the Failsafe Baud Rate option is set to 115200.
Remote Terminal Type	Sets the remote console terminal type. By default, the Remote Terminal
	Type option is set to VT 100/VT 220.
Redirection After Boot	Enables or disables the BIOS console redirection when the operating
	system is loaded. By default, the Redirection After Boot option is set to
	Enabled.
