After you configure the ports, configure the terminal settings by performing the following steps:

1. In HyperTerminal, click File, click Properties, and select the Settings tab.

2. Ensure that the Function, arrow, and ctrl keys act as field is set to Terminal Keys.

3. Ensure that the Backspace key sends field is set to Ctrl+H.

4. Change the Emulation setting from Auto detect to ANSI or VT100/220.

This setting should be the same as the setting you selected for the Console Redirection option on the server.

When you click Terminal Setup, you should see a setting for the number of rows and columns.

5. Change the number of rows from 24 to 25 and leave the number of columns at 80.

If you do not have these settings, you must upgrade your terminal emulation software.

Rebooting the System

Console redirection is designed to yield control of the serial ports to the operating system. This configuration allows serial

debugging and redirection of the operating system to function correctly without interference from the system BIOS.

To use console redirection to shut down a system and troubleshoot it or to change SCSI BIOS configurations, perform the

following steps:

1. Reboot the system. See

Table C-4

for a recommendation on how to do this.

2. When the system begins to reboot, use console redirection to watch and interact with the system during the POST.

While the system is booting, you can do the following:

Enter the System Setup program

Enter the SCSI setup menus

Update the firmware and the BIOS (flash the system)

Configuring Special Keys

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 functions. You can emulate a function key or control key by using a special key sequence,

called an escape sequence, to represent a specific key.

For console redirection, an escape sequence starts with an escape character. This character can be entered in a number of

different ways, depending on the requirements of your terminal emulation software. For example, 0x1b, ^[, and <Esc> all

refer to the same escape character. Some terminal software uses predefined macros to send the proper escape sequences. In

HyperTerminal, you can define macros by selecting Key Macros from the View menu. Macros can be assigned to almost any

possible key for almost any key combination. Create a macro for each of your function keys.

Table C-2

lists the VT100/220 escape sequences and

Table C-3

lists the ANSI-supported escape sequences that must be set

to represent a special key or command.

NOTE:

When defining macros in HyperTerminal, you must press <Ins> before <Esc> to signify that you are sending

an escape sequence rather than escaping out of the dialog box. If you do not have these settings, this is an indication

that you must upgrade your terminal emulation software.
