b. Configure the Baud rate, Parity, and Stop bits fields to match the serial
port settings on the server.
Notes:
1) Serial redirection does not support hardware-based flow control. Disable
the terminal flow control.
2) To prevent buffer overrun and character loss, configure both serial ports
with the same baud rate. The Remote Supervisor Adapter II provides a
512-character buffer on both incoming and outgoing serial streams.
4.
In the Serial Port 2 area, set the following values for the fields:
a. In the Port function field, select Serial redirect.
b. Configure the Baud rate, Parity, and Stop bits fields to match the serial
port settings on the server.
Note: Serial redirection does not support hardware-based flow control.
Disable the terminal flow control.
5. Select the Serial pass-thru to Port 1 check box to force the link between
COM1 and COM2. Both ports must be active and in serial redirection mode to
enable this function. If the function is not enabled, the command-line interface
must be invoked, and the console command must be used to link the
appropriate ports together.
Serial-to-Telnet redirection
Serial-to-Telnet redirection enables a system administrator to use the Remote
Supervisor Adapter II as a serial terminal server. Either one or both serial ports can
be accessed from a Telnet connection when serial redirection is enabled.
For serial redirection quick setup information, see “Serial redirection quick setup” on
page 86.
The Remote Supervisor Adapter II uses the custom command-line interface enter
key sequence to return from a serial redirection session. The command-line
interface enter key sequence defaults to the Microsoft Windows Server 2003
emergency management services compatible key sequence: Press the Escape key,
then the open parenthesis symbol [ ( ].
Notes:
1. The Remote Supervisor Adapter II allows two open Telnet sessions. The Telnet
sessions can independently access the serial ports so that multiple users can
have a concurrent view of a redirected serial port.
2. One serial port must be enabled for serial redirection to enable the console
command.
3. Telnet does not use the command-line interface exit key sequence. The
command-line interface console command must be used to select a COM port.
4. The Telnet session is authenticated through the local logon profiles or through
an LDAP server.
