Embodiment Construction

[0014] Such as figure 2 As shown, it is a diagram of the operating structure of the serial port signal identification system in the preferred embodiment of the present invention. The serial port signal identification system 41 runs in the baseboard management controller 4 installed in the server 1 . The server 1 also includes a serial port 2 , a UART3 (Universal Asynchronous Receiver / Transmitter: Universal Asynchronous Receiver / Transmitter), a south bridge chip 5 and an operating system 6 .

[0015] The UART3 transmits the signal entering from the serial port 2 to the cache 40 of the baseboard management controller 4, so that the serial port signal recognition system 41 reads the signal from the cache 40, and sends the signal according to the type of the signal. The signal is sent to the baseboard management controller 4 for direct processing or transmitted to the operating system 6 through the south bridge chip 5 for processing. The serial port signal identification system...

Abstract

The invention discloses a system for identifying serial interface signal, which operates in a substrate management controller. The substrate management controller is positioned in a server. The system comprises a reading module for periodically reading signal entering from a serial interface of the server from a cache of the substrate management controller, an identifying module for identifying the read signal and judging whether the read signal is a terminal mode instruction processed by the substrate management controller, and a processing module for transmitting the terminal mode instruction to be processed by a processing program for processing the terminal mode instruction in the substrate management controller when the read signal is the terminal mode instruction, and further for transmitting the read signal to be processed by an operation system of the server through a south bridge chip of the server when the read signal is not the terminal mode instruction. The invention further provides a method for identifying serial interface signal.

Description

technical field [0001] The invention relates to a serial port signal identification system and method. Background technique [0002] Server manufacturers have developed the Intelligent Platform Management Interface (IPMI) standard for cross-platform system management since 1998. The purpose is to provide servers with hot swap, monitoring, alarms, logs, assets, security, and remote maintenance. and other management functions. Wherein, all IPMI functions are accomplished by sending terminal mode commands to a Base Board Management Controller (BMC). Signals input from the server serial port include signals processed by the operating system and terminal mode commands processed by the baseboard management controller. Signals processed by the operating system need to pass through a Super I / O (Super Input / Output, super input and output) chip and be transmitted to the operating system through the south bridge chip for processing. The terminal mode commands processed by the BMC ne...
