Abstract:
A baseboard management controller (BMC) connects with a COM serial port. The BMC includes an input queue and an output queue. If a basic input output system (BIOS) of the BMC has been initialized, the COM serial port is used by the BIOS. When a processor of the BMC sends a control command to a sharing system of the BMC, the input queue and the output queue are converted to time division multiplex (TDM) queues. The COM serial port may be used by the BIOS or by the BMC according to an ID flag of each element of the TDM queues.
