Get Serial/Modem Configuration Command: Net Function=0Ch, Command=11h
Request Data
Response Data
Setting the Super I/O's serial port parameters varies as to which part of the operational sequence is
desired to be buffered: BIOS or system.
BIOS message buffering must be configured from the BIOS Setup screen that deals with Remote
Access. This is usually available from the Main BIOS Setup menu. The port must be set to COM2
and the Baud Rate and Flow Control must match what is sent to the IPMC via the Set Serial/
Modem Configuration command shown above.
System message buffering, such as Linux, requires that the system have a driver that can route
system messages to the COM2 port. For Linux, this port is usually /dev/ttyS1. Linux can be
configured to route the output of syslog to various places, including /dev/ttyS1, via the file /etc/
syslog.conf. Refer to the man page for syslog.conf for more details. Setting the operating
parameters of the serial port under Linux can be accomplished with the stty command (e.g., stty –F
/dev/ttyS1 19200). The serial port parameters should be configured in a startup script that the
system executes when it starts up. As with the BIOS description above, both the Baud Rate and
Flow Control parameters must match those set in the IPMC.
