3.20 Console Redirection
The BIOS supports redirection of both video and keyboard via a serial link (serial port). When
console redirection is enabled, the local (host server) keyboard input and video output are
passed both to the local keyboard and video connections, and to the remote console through
the serial link. Keyboard inputs from both sources are considered valid and video is displayed to
both outputs.
As an option, the system can be operated without a host keyboard or monitor attached to the
system and run entirely via the remote console. Utilities that can be executed remotely include
BIOS Setup.
3.20.1 Serial Configuration Settings
The BIOS does not require that the splash logo be turned off for console redirection to function.
The BIOS supports multiple consoles, some of which are in graphics mode and some in text
mode. The graphics consoles can display the logo and the text consoles receive the redirected
text.
Console redirection ends at the beginning of the legacy operating system boot. The operating
system is responsible for continuing the redirection from that point.
3.20.2 Keystroke Mappings
During console redirection, the remote terminal sends keystrokes to the local server. The
remote terminal can be a dumb terminal with a direct connection and running a communication
program. The keystroke mappings follow VT-UTF8 format with the following extensions.
3.20.2.1 Setup Alias Keys
The <Del> and <Ctrl>-function key combinations are synonyms for the <F2> or “Setup” key.
They are implemented and documented, but are not be prompted for in screen messages.
These hot keys are defined for console redirection support, and are not be implemented for
locally attached keyboards.
3.20.2.2 Standalone <Esc> Key for Headless Operation
The Microsoft Headless Design Guidelines describes a specific implementation for the <Esc>
key as a single standalone keystroke:
<Esc> followed by a two-second pause must be interpreted as a single escape.
<Esc> followed within two seconds by one or more characters that do not form a
sequence described in this specification must be interpreted as <Esc> plus the character
or characters, not as an escape sequence.
The escape sequence in the following table is an input sequence. This means it is sent to the
BIOS from the remote terminal.
