Ipmi Serial Interface; Table 41. Console Redirection Escape Sequences For Headless Operation - Intel X38ML - Server Board Motherboard Technical Manual

Intel® Server Board X38ML
<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.

<Esc>R<Esc>r<Esc>R
This item is set to "disable" by default.
5.23.2.3 Limitations
BIOS Console redirection terminates after an EFI-aware operating system calls EFI Exit
Boot Services. The operating system is responsible for continuing console redirection
after that.
BIOS console redirection is a text console. Graphical data, such as a logo, is not
redirected.
5.23.2.4 Interface to Server Management
If the BIOS determines that console redirection is enabled, it reads the current baud rate and
passes this value to the appropriate management controller via the Intelligent Platform
Management Bus (IPMB).
5.23.3

IPMI Serial Interface

The system provides a communication serial port with the BMC. A multiplexer, controlled by the
BMC, determines if the COM1 external connector is electrically connected to the BMC or to the
standard serial port of the Super I/O. See Section 14, titled "IPMI Serial/Modem Interface", in the
Intelligent Platform Management Interface Specification, Version 2.0, for information about
these features.
5.23.3.1 Channel Access Modes
The BIOS supports the four different channel access modes described in Table 6-4 of the
Intelligent Platform Management Interface Specification, Version 2.0.
5.23.3.2 Interaction with BIOS Console Redirection
BIOS Console Redirection provides VT-UTF8 console redirection support in Intel's server BIOS
products. This implementation meets the functional requirements set forth in the Microsoft
Windows 2003* WHQL requirements for headless operation of servers. It also maintains a
necessary degree of backward compatibility with existing Intel
meets the architectural requirements of Intel server products in development.
The server BIOS has a console that interacts with a display and keyboard combination. The
BIOS instantiates sources and input/output data in the form of BIOS Setup screens, Boot
