    							Advanced Configuration of the DRAC 561
    The connect -h com2 command displays the contents of the serial 
    history buffer before waiting for input from the keyboard or new characters 
    from the serial port.
     NOTE: When using the -h option, the client and server terminal emulation type 
    (ANSI or VT100) must be identical; otherwise, the output may be garbled. 
    Additionally, set the client terminal row to 25.
    The default (and maximum) size of the history buffer is 8192 characters. 
    You can set this number to a smaller value using the command:
    racadm config -g cfgSerial -o cfgSerialHistorySize

    Connecting to the Managed System Through the 
    Local Serial Port or Telnet Management Station 
    (Client System)
    The managed system provides access between the DRAC 5 and the serial port 
    on your system to enable you to power on, power off, or reset the managed 
    system, and access logs.
    The serial console is available on the DRAC 5 through the managed system 
    external serial connector. Only one serial client system (management station) 
    may be active at any given time. The telnet and SSH consoles are available on 
    the DRAC 5 through the DRAC modes (see DRAC Modes on page 91). Up 
    to four telnet client systems and four SSH clients may connect at any given 
    time. The management station connection to the managed system serial or 
    telnet console requires management station terminal emulation software. See 
    Configuring the Management Station Terminal Emulation Software on 
    page 65 for more information.
    The following subsections explain how to connect your management station 
    to the managed system using the following methods:
    • A managed system external serial port using terminal software and a DB-9 
    or a null modem cable
    • A telnet connection using terminal software through the managed system 
    DRAC 5 NIC or the shared, teamed NIC

    Connecting the DB-9 or Null Modem Cable for the 
    Serial Console
    To access the managed system using a serial text console, connect a DB-9 null 
    modem cable to the COM port on the managed system. Not all DB-9 cables 
    carry the pinout/signals necessary for this connection. The DB-9 cable for this 
    connection must conform to the specification shown in Table 4-11.
     NOTE: The DB-9 cable can also be used for BIOS text console redirection.
    Configuring the Management Station Terminal 
    Emulation Software
    Your DRAC 5 supports a serial or telnet text console from a management 
    station running one of the following types of terminal emulation software:
    • Linux Minicom in an Xterm
    • Hilgraeve’s HyperTerminal Private Edition (version 6.3)
    • Linux Telnet in an Xterm
    •Microsoft Telnet
    Perform the steps in the following subsections to configure your type of terminal 
    software. If you are using Microsoft Telnet, configuration is not required.
