To configure the serial data-transfer rate and redirection, complete the following steps: 1. Log in to the IMM on which you want to configure the serial port. For more information, see Chapter 2, "Opening and using the IMM Web interface," on page 9. 2. In the navigation pane, click Serial Port. 3. In the Baud rate field, select the data-transfer rate to match the rate of the server COM port that you want to use for serial redirection. Use the Baud rate field to specify the data-transfer rate of your serial port connection. To set the baud rate, select the data-transfer rate, in bits per second, that corresponds to your serial port connection. 4. In the CLI mode field in the Serial Redirect/CLI Settings area, select CLI with EMS compatible keystroke sequences if you want to use the Microsoft Windows Server 2003 Emergency Management Services (EMS) compatible key sequence to exit the serial redirection operation, or select CLI with user defined keystroke sequences if you want to use your own key sequence. Note: If you select CLI with user defined keystroke sequences, you must define the key sequence. After the serial redirection starts, it continues until the user types the exit key sequence. When the exit key sequence is typed, serial redirection stops and the user is returned to command mode in the Telnet or SSH session. Use this field to specify the exit key sequence. 5. Click Save. Serial-to-Telnet or SSH redirection Serial-to-Telnet or SSH redirection enables a system administrator to use the IMM as a serial terminal server. A server serial port can be accessed from a Telnet or SSH connection when serial redirection is enabled. Notes: 1. The IMM allows a maximum of two open Telnet sessions. The Telnet sessions can access the serial ports independently so that multiple users can have a concurrent view of a redirected serial port. 2. The command-line interface console 1 command is used to start a serial redirection session with the COM port. Example session telnet 192.168.70.125 (Press Enter.) Connecting to 192.168.70.125... username: USERID (Press Enter.) password: ******** (Press Enter.) system> console 1 (Press Enter.) All traffic from COM2 is now routed to the Telnet session. All traffic from the Telnet or SSH session is routed to COM2. ESC Q Type the exit key sequence to return to the command-line interface. In this example, press Esc and then type q.

To configure the serial data-transfer rate and redirection, complete the following
steps:
1.
Log in to the IMM on which you want to configure the serial port. For more
information, see Chapter 2, “Opening and using the IMM Web interface,” on
page 9.
2.
In the navigation pane, click
Serial Port
.
3.
In the
Baud rate
field, select the data-transfer rate to match the rate of the
server COM port that you want to use for serial redirection.
Use the
Baud rate
field to specify the data-transfer rate of your serial port
connection. To set the baud rate, select the data-transfer rate, in bits per second,
that corresponds to your serial port connection.
4.
In the
CLI mode
field in the
Serial Redirect/CLI Settings
area, select
CLI with
EMS compatible keystroke sequences
if you want to use the Microsoft
Windows Server 2003 Emergency Management Services (EMS) compatible key
sequence to exit the serial redirection operation, or select
CLI with user
defined keystroke sequences
if you want to use your own key sequence.
Note:
If you select
CLI with user defined keystroke sequences
, you must
define the key sequence.
After the serial redirection starts, it continues until the user types the exit key
sequence. When the exit key sequence is typed, serial redirection stops and the
user is returned to command mode in the Telnet or SSH session. Use this field
to specify the exit key sequence.

Serial-to-Telnet or SSH redirection
Serial-to-Telnet or SSH redirection enables a system administrator to use the IMM
as a serial terminal server. A server serial port can be accessed from a Telnet or
SSH connection when serial redirection is enabled.
Notes:
1.
The IMM allows a maximum of two open Telnet sessions. The Telnet sessions
can access the serial ports independently so that multiple users can have a
concurrent view of a redirected serial port.
2.
The command-line interface
console 1
command is used to start a serial
redirection session with the COM port.
Example session
telnet 192.168.70.125 (Press Enter.)
Connecting to 192.168.70.125...
username: USERID (Press Enter.)
password: ******** (Press Enter.)
system> console 1 (Press Enter.)
All traffic from COM2 is now routed to the Telnet session. All traffic from the
Telnet or SSH session is routed to COM2.
ESC Q
Type the exit key sequence to return to the command-line interface. In this
example, press Esc and then type
q
.
