Serial Communication details
The Serial Communication screen provides the following options.
Option
Description
Serial
Communication
Selects 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 devices. 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 is not changed. This
option is set to 115200 by default.
Remote Terminal
Type
Sets the remote console terminal type. This option is set to ANSI VT100/VT220 by default.
