Installation Manual
Advanced iDRAC6 Configuration 87
To connect to the managed system text console, open an iDRAC6 command 
prompt (displayed through a Telnet or SSH session) and type:
console com2
The console -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.
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 
<number>
To configure Linux for console direction during boot, see "Configuring Linux 
for Serial Console During Boot" on page 91.
Using a Telnet Console
Running Telnet Using Microsoft Windows XP or Windows 2003
If your management station is running Windows XP or Windows 2003, 
you may experience an issue with the characters in an iDRAC6 Telnet session. 
This issue may occur as a frozen login where the return key does not respond 
and the password prompt does not appear. 
To fix this issue, download hotfix 824810 from the Microsoft Support website 
at support.microsoft.com. See Microsoft Knowledge Base article 824810 for 
more information. 
Running Telnet Using Windows 2000
If your management station is running Windows 2000, you cannot access 
BIOS setup by pressing the <F2> key. To fix this issue, use the Telnet client 
supplied with the Windows Services for UNIX 3.5—a recommended free 
download from Microsoft. Go to microsoft.com/downloads/ and search for 
Windows Services for UNIX 3.5.
