164 Using the Serial and racadm Commands

Starting a Text Console

After you have logged into the DRAC 4 through your management station

terminal software or by telnet, you can redirect the managed system text

console by using connect com2, which is a serial/telnet command. Only one

connect com2 client is supported at a time (out of four total sessions shared

with the DRAC 4 Web-based interface).

To connect to the managed system text console, type connect com2 from

the DRAC 4 command prompt (displayed through Minicom or

HyperTerminal).

NOTE: When accessing a DOS console through connect com2, characters in the

output may be dropped during the output of large amounts of data (for example, the

dump of large files greater than 30 lines). This can cause incorrect displays in

connect com2 over telnet sessions. Red Hat Enterprise Linux and the Microsoft

Windows Special Administration Console (SAC) work correctly.

connect com2 also supports the -h option. This option displays the history of

the last characters written to the text console. 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

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: The terminal emulation type (ANSI or VT100) of the client terminal must

match the type on the server serial port output when using the -h option; otherwise,

the output may be garbled. In addition, the number of rows and columns of the

client terminal must be set to 25.
