Configuring Console Redirection on the System
Configuring Console Redirection on the Client System
Console redirection allows you to maintain a system from a remote location by re-directing keyboard input and text output through the serial port. Graphic output is not redirected. Console redirection can be used under MS-DOS® for tasks such as setting up a common BIOS configuration or setting up a RAID configuration. In a typical installation, the system is connected to a port concen-trator that allows you to connect several systems using a shared modem. After you use a modem or other remote connection to log into the port concentrator, you can select which system you want to manage with console redirection. This section describes the simplest connection possible: connecting to a system with a null modem cable.
To use console redirection, you must have the following:
This port must not conflict with any other ports on the system.
For systems with two available serial ports, you can use either the COM 1 or COM 2 port.
Your remote terminal emulation software should meet the following specifications:
All versions of the Microsoft® Windows® operating systems come with Hyper-Terminal terminal emulation software. However, the version of HyperTerminal included with most Windows operating systems does not provide the correct screen size, the arrow and function keys do not work, and there is no method of creating macros. Dell recommends that you either upgrade your version of HyperTerminal to HyperTerminal Private Edition 6.1 or later or select new terminal emulation software.
Console redirection is configured through the System Setup program (see "Using the System Setup Program" for instructions). The Console Redirection option displays a screen that allows you to configure console redirection. The submenu allows you to turn the feature on or off, select the remote terminal type, and enable or disable redirection after booting. The options available are listed in Table C-1.
|
Selection |
Options |
Console Redirection | Systems with one serial port: Systems with two serial ports: |
Remote Terminal Type | VT 100/220 |
Redirection after boot | Enabled |
If you select VT 100/220 but not all the characters are visible on the screen, go back to the System Setup program and select ANSI as your terminal type. ANSI can display the full set of ASCII characters.
 |
NOTE: The examples in this document assume that you have upgraded to Hilgraeve's HyperTerminal Private Edition 6.1 or later. If you are using other terminal emulation software, see the help file for that software. |
If no COM port is available and you do not have a Dell™ system, you need to contact technical support for your client system.
After you have selected an available COM port, the COM port properties window is displayed.
Console redirection supports 9600, 19.2 K, 57.6 K, or 115.2 K bps.
After you configure the ports, configure the terminal settings by performing the following steps:
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.
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 BIOS configurations, perform the following steps:
|
NOTE: To use console redirection to run utilities on the utility partition, the utility partition must have been created using Dell OpenManage™ Server Assistant version 6.3.1 or later. |
Console redirection uses ANSI or VT 100/220 terminal emulation, which are limited to basic ASCII characters. Function keys, arrow keys, and control keys are not available 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 and Table C-3 list the VT 100/220 escape sequences that must be sent 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. |

F12 | <Esc> <Shift>oa |
After you create these macros, pressing <F1> on the keyboard while running the terminal emulation software sends <Esc><Shift>op to the server. When these three characters are transmitted, the server interprets them as <F1>. You need this functionality to change the settings in the System Setup program or to continue if there is an error on your system and you are prompted to press <F1>.
In addition to macros for the function keys, Dell recommends that you set up macros for the additional escape sequences listed in Table C-4.
