IPMI Messaging Communication Settings
These parameters are the global settings for IPMI messaging, which include Direct Connect and
Modem modes. IPMI messaging always occurs with 8 bits/character, no parity, and 1 stop bit. The
COM settings that can be configured are:
Flow Control: This option sets how the flow of data is controlled. Available choices are No
Flow Control, CTS/RTS (hardware handshake), and XON/XOFF.
Baud Rate: This option sets the maximum rate in bits per second at which the data can be
transmitted through the serial port. Available baud rates are 9600, 19200, 38400, 57600, and
115200 bps. Support for baud rates higher than 19200 is optional and SMU will only display
those that the BMC supports.
Enable Data Terminal Ready (DTR) Hang-up: When DTR Hang-up is enabled, hang-up of a
modem connection is based on when the DTR signal becomes inactive. When this is enabled,
the modem settings Modem Hang-up and Escape Sequences are not used.
Modem Mode Configuration
If Modem Mode is chosen as the connection mode in Serial/Modem Channel Configuration screen
and the user clicks Next, the Modem Mode Configuration screen is displayed. This mode is for
applications that connect to the server via an external modem. The Modem Mode Configuration
screen is displayed below.
After completing this screen, click Next to move to the next screen to continue this sub-task.
Modem Init String
Enter the ASCII string used to initialize the modem. This string is typically set to
ATE1Q0V1X4&D2&C1S0=0. The length of this string is platform-dependent; for this server, the
length is 48 bytes, including a termination character (this edit box will only allow a maximum of 47
characters to be entered because of the need for a termination character). The BMC automatically
follows this string with an <Enter> character or carriage return.
