Intel® Server Platforms SR6850HW4 and SR6850HW4/M Product Guide
Keystroke Mappings
During console redirection, the remote terminal (which may be a dumb terminal or a system with a
modem running a communication program) sends keystrokes to the local server. The local server
passes video back over this same link. The keystroke mappings follow VT-UTF8 format with the
following extensions.
Setup Alias Keys
The <Del> and <Ctrl>-<function key> combinations are synonyms for the <F2> or “Setup” key.
These are not prompted for in screen messages. These hotkeys are defined only for Console
Redirection support, and are not used on locally attached keyboards.
Standalone <Esc> Key for Headless Operation
To complete an escape sequence, the timeout must be two seconds for entering additional
characters following an escape.
<Esc> followed by a two-second pause is interpreted as a single escape.
<Esc> followed within two seconds by one or more characters that are not forming a sequence
described in this document are interpreted as <Esc> plus the character or characters, not an
escape sequence.
All of the following escape sequences are input sequences, that is, they are sent to the BIOS from
the remote terminal.

BMC Mux Switch escape sequence
<Esc>CDZt<terminal-type-number>
Dynamic Terminal Type Choice, where
0 = PC-ANSI (the only current terminal type)
1 = VT100 (not implemented, but honored as VT100+)
2 = VT100+
3 = VT-UTF8
<Esc>-CDZ0
Inhibit Console Redirection
<Esc>-CDZ1
Restart Console Redirection
<Esc>-CDZ2
“Soft” Inhibit Console Redirection, without serial port or
modem reset
Limitations
BIOS Console redirection terminates after an EFI-aware operating system calls EFI Boot Service
ExitBootServices. The operating system is responsible for continuing the Console Redirection after
that point. BIOS console redirection is a text console and any graphical data such as a logo are not
redirected.
