Standalone <Esc> Key for Headless Operation
The Microsoft Headless Design Guidelines describes a specific implementation for the
<
Esc
> key as a single standalone keystroke:
To complete an escape sequence, the timeout must be two seconds for entering addi-
tional characters following an escape.
<
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 char-
acter 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.
Reset
BIOS provides another friendly method to reset system from console. User could use
<
Ctrl
> + <
Shift
> + ‘-’ to reboot system from remote console.
Limitations
BIOS Console redirection terminates after an operating system has being loaded.
The operating system is responsible for continuing console redirection after that.
BIOS console redirection is a text console. Graphical data, such as a logo, are not
redirected.
