authentication of type straight password, MD2, MD5, and none. (Refer to the IPMI specification for
more information on these authentication types.)
Basic mode is enabled, allowing basic serial communications to take place over the serial/modem
channel.
Session inactivity timeout is set to one minute.
Session termination bits are enabled to enable ending of a serial/modem session if an inactivity
timeout occurs or if DCD is lost.
Flow control and baud rate are set for IPMI messaging (flow control is set to hardware flow control;
the baud rate is set to 19.2 kbps).
The multiplexor that determines who controls the serial connector has various default settings enabled
and disabled.
Modem Mode Configuration View
If Modem Mode is chosen in the serial/modem channel configuration initial view, then when the Next
button is clicked, the view shown in Figure 49 is displayed. This mode is for applications that connect
to the server via an external modem.
Figure 49. Modem Settings
Modem Init String
This setting is an ASCII string used to initialize the modem. This string is typically set to
"ATE1Q0V1X4&D2&C1S0=0" and is 64 bytes maximum, including a termination character. The BMC
automatically follows this string with an <Enter> character or carriage return.
Modem Escape Sequence
This setting is an ASCII string representing the Escape string to be sent to the modem before sending
a command string. This string is five-bytes maximum in length and it is typically set to "+++" . Note
that if this parameter is left empty, the default "+++" sequence is used by the BMC. The modem
escape sequence is not sent to the modem if DTR Hang-up is enabled;
Hang-up Sequence
This setting is an ASCII string that is sent to the modem to terminate the session. The BMC automatically
follows this string with an <Enter> character when sending it to the modem. This string is 8 bytes max
and it is typically set to "ATH" . Note that if this parameter is left empty, the default "ATH" sequence
is used by the BMC. The hang-up sequence is not sent to the modem if DTR Hang-up is enabled;
