Console Redirection
The BIOS supports redirection of video output and keyboard input via serial link. This section details
the serial redirection scheme. For redirection over LAN (Serial over LAN or SOL), see the ISM online
help.
When console redirection is enabled, local (host server) keyboard input and video output are passed
both to the local keyboard and video connections, and to the remote console via the serial link. Keyboard
inputs from both sources are considered valid and video is displayed to both outputs.
With console redirection, you can operate the server system without having a keyboard or monitor
attached to it. Setup and any other text-based utilities can be accessed via console redirection. Note
that serial redirection uses PC-ANSI and the UART settings assume 1 stop bit.
Operation
NOTE
When console redirection is enabled, the text on the local console screen will draw slowly when it is
operating under EFI. This is especially true when a low baud-rate modem is used, such as the default
baud rate of 19.2K. This is because EFI is not an interrupt-driven environment and it uses a polling
mechanism to communicate with the remote console.
When redirecting through a modem, as opposed to a null modem cable, the modem needs to be
congured as follows:
• Auto-answer (for example, ATS0=2, to answer after two rings).
• Modem reaction to DTR set to return to command state (such as AT&D1). Failure to provide
the modem reaction results in the modem either dropping the link when the server reboots (as
in AT&D0) or becoming unresponsive to server baud rate changes (as in AT&D2).
• The Setup/EMP option for handshaking must be set to CTS/RTS + CD for optimum
performance. The CD refers to carrier detect. If the EMP is sharing the COM port with
serial redirection, the handshaking must be set to CTS/RTS+ CD. In selecting this form of
handshaking, the server is prevented from sending video updates to a modem that is not
connected to a remote modem. If this is not selected, video update data being sent to the
modem inhibits many modems from answering an incoming call. An EMP option utilizing CD
should not be used if a modem is not used and the CD is not connected.
Once console redirection is selected via Setup, redirection binary is loaded into memory and
activated during POST. While redirection cannot be removed without rebooting, it can be
inhibited and restarted.
Inhibiting and restarting is accomplished through an INT 16h mechanism. The standard INT 16h
(keyboard handler) function ah=05h places a keystroke in the key buffer, as if an actual key is
pressed. Keystrokes buffered this way are examined by redirection; if a valid command string
has been sent, it is executed. The following commands are supported:
• Esc-CDZ0 - Inhibit Console Redirection. In order to inhibit redirection, the software must call
INT 16h, function ah=05h ve times to place the ve keys in the key buffer. Keystrokes sent
to the INT 16h buffers to invoking a command are buffered, and should be removed through
normal INT 16h calls to prevent these keystrokes from being passed to another application.
When redirection is inhibited, the serial port is released and can be used by other applications.
• Esc-CDZ1 - Restart Console Redirection. Restarting reclaims the serial port and continues
redirection
