A method and apparatus is provided for serial port redirection using a management controller. A serial controller is selectively coupled with a management controller to facilitate the redirection of serial information. The management controller includes a packetizer to packetize the serial information. The packetized information may be communicated to remote computing devices over a network connection or a management bus. The management controller receives both redirection and non-redirection packets from the communication channel. If the management controller receives redirection packets from a remote computing device, it formats the redirection packets as a stream of serial information and communicates the stream of serial information to the serial controller.

Serial port redirection using a management controller

System and method in a USB environment for providing secondary management channel access to a managed system via a communications device connected to the managed system. The communications device can be shared between management channel use and system use. A remote management system can connect directly to the platform management subsystem of the managed system and the channel provides a communications path to the platform management subsystem under conditions where the host processor(s) and system software are unavailable. A management controller simulates the presence of the communication device to the USB host when the management controller takes ownership of the communication device. For non-USB communication devices, the management controller also converts data from non-USB format to USB format and routes the converted data to the USB host.
