Console redirection uses ANSI or VT100/220 terminal emulation, which are limited to basic ASCII characters. There are no function keys, arrow keys, or control keys in this character set. However, most BIOS software requires the use of function keys and control keys for ordinary actions. Specific function keys and escape keys can be emulated by using a special key sequence, called an escape sequence, to represent a specific key.
Use the Escape sequences, listed in the following table, for keys while setting console redirection in BIOS through serial port. These keys are also listed during BIOS POST. Press the spacebar to pause and view the list. Supported sequences are also listed in the history of the system's telnet client.
