In addition to the normal environmental management functions the baseboard management controller (BMC) design for the server requires supporting serial over a Local Area Network as well as local terminal emulation or Emergency Management Protocol (EMP). In addition to these functions, Linux requires a terminal emulation program to be attached locally so the users can run a remote application using a terminal server. These installations require the terminal server emulation mode of operation where the Linux text is directed to either a serial port or over the LAN to a proxy application somewhere in the network. The following design provides a combination of functions depending on the customer requirements for the operating system. The serial interface design provides the normal serial port function. The circuitry also provides an interface into the BMC for monitoring and controlling the environmental conditions of the server, a remote serial connection over (LAN), and a terminal emulation function in conjuction with the BMC function for concurrent Linux operation and environmental control.
