Console Redirection

The console redirection allows a remote user to diagnose and fix problems
on a server, which has not successfully booted the 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.
