Using the BMC Management Utility 79
When BIOS console redirection to serial port is enabled on the remote
managed system, any application that uses the BIOS to read from or write
to the system console will have its I/O redirected to the designated
serial I/O port. When SOL is activated, the BMC firmware reads any data
written to the serial port and transmits it to the SOL Proxy as LAN packets.
SOL Proxy then forwards the data to the telnet client as TCP/IP packets.
Conversely, any keyboard activity at the telnet client is sent to the BMC by
SOL Proxy. BMC then writes the packets to the system serial I/O port.
NOTE: See your system’s User’s Guide for more information about console
redirection, including hardware and software requirements and instructions for
configuring host and client systems to use console redirection.

The SOL Proxy communication scheme enables you to view and configure
the BIOS settings of a managed system, as well as to reset the managed
system remotely using a telnet client. SOL Proxy is installed as a daemon
service and automatically starts each time the system boots. SOL Proxy can
accommodate only one telnet session at a time.
