BIOS Setup Options at Boot
You can initiate SETUP by pressing the respective keys during the POST:
<F2> Enter the BIOS Setup
Console Redirection
The console redirection allows a remote user to diagnose and fix problems on
a server, which has not successfully booted the operating system (OS). The
centerpiece of the console redirection is the BIOS Console. The BIOS
Console is a Flash ROM-resident utility that redirects input and output over
a serial or modem connection.
The BIOS supports console redirection to a serial port. If serial port based
headless server support is provided by the system, the system must provide
support for redirection of all BIOS driven console I/O to the serial port. The
driver for the serial console must be capable of supporting the functionality
documented in the ANSI Terminal Definition.
Enable/Disable Console Redirection
The console redirection function can be enabled/disabled in the BIOS Setup
menu.

COM2 for Serial over LAN
Configuring Special Keys
Console redirection uses ANSI terminal emulation, which is limited to basic
ASCII characters. There are no function keys, arrow keys, or control keys in
this character set. However, the PowerEdge C5000 software requires the use
of function keys and control keys for ordinary functions. You can emulate a
function key or control key by using a special key sequence called an escape
sequence, to represent a specific key.
