Console Redirection

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