Referring to fig. 1, fig. 1 is an embodiment of a method for interaction between an intelligent serial port screen and a BMC provided in the present application, where the method includes:
101. the BMC receives a target switching instruction sent by the front panel;
in this embodiment, a target switching instruction may be generated by pressing a physical button of the front panel, and after the front panel generates the target switching instruction, the target switching instruction is sent to the BMC, so that the BMC receives the target switching instruction. Alternatively, the BMC may receive the target switching instruction sent by the front panel through the wireless network.
102. The BMC controls the signal switcher to establish communication connection between a first UART interface of the BMC and a first USB interface of the front panel according to the target switching instruction;
in this embodiment, after receiving the target switching command, the BMC controls the signal switch to switch the signal channel according to the target switching command. Thereby establishing communication connection between the first UART interface of the BMC and the first USB interface of the front panel according to the signal channel switching. For example, when the signal switch is a multi-phase channel signal switch including at least channels No. 1, no. 2, and No. 3, the first UART interface of the BMC may be configured to be connected to the channel No. 1, and the first USB interface of the front panel may be configured to be connected to the channel No. 3. When a target switching command is received, the BMC controls the signal switcher to switch the signal channel according to the target switching command and communicate the channel No. 1 and the channel No. 3, so that the signal switcher establishes communication connection between a first UART interface of the BMC and a first USB interface of the front panel.
103. The intelligent serial port screen establishes communication connection with the front panel through a second UART interface and a second USB interface of the front panel, and the intelligent serial port screen is provided with the second UART interface;
in this embodiment, the intelligent serial port screen is mounted on the front panel through a movable hanging buckle, for example, the intelligent serial port screen can be hung in front of the front panel, or can be operated by hand. The intelligent serial port screen is provided with a second UART interface. The front panel is provided with a second USB interface. The intelligent serial port screen and the front panel establish communication connection through a second UART interface and a second USB interface, specifically, the second UART interface of the intelligent serial port screen is connected into the second USB interface of the front panel through a UART-to-USB cable, so that the communication connection between the intelligent serial port screen and the front panel is established.
104. And the intelligent serial port screen establishes interaction with the BMC through the first UART interface, the first USB interface, the second USB interface and the second UART interface according to a target authentication handshake protocol.
In this embodiment, the communication connection between the first UART interface of the BMC and the first USB interface of the front panel and the communication connection between the second USB interface of the front panel and the second UART interface of the intelligent serial port screen are established, so that a communication path from the intelligent serial port screen to the front panel and then to the intelligent serial port screen is established. Then, the intelligent serial screen is in communication connection with the BMC according to the target authentication handshake protocol, so that interaction between the intelligent serial screen and the BMC is established. Specifically, the target authentication handshake protocol may be a reply handshake protocol, for example, firstly, a handshake encryption key of a current BMC is input into an intelligent serial port screen, and after a signal channel is switched by a BMC control signal switcher to complete connection from a second USB interface of the intelligent serial port screen to a first UART interface of the BMC, the encryption handshake code is sent to the first UART interface. The encryption method may be, but not limited to, encryption by an advanced encryption standard (Advanced Encryption Standard, AES) or a data encryption algorithm (Data Encryption Algorithm, DEA).

Alternatively, the target authentication handshake protocol may be another protocol, and is not limited herein.
In this embodiment, after communication interaction from the intelligent serial port screen to the BMC is established, state information of the BMC, such as log information, system detection information, heat dissipation information, etc., may be obtained through the intelligent serial port screen, or may be set through the intelligent serial port screen, or may be modified through the intelligent serial port screen.

Therefore, when information is required to be acquired in an interactive manner with the BMC, the intelligent serial port screen is not required to be embedded into the front panel to be fixedly connected with the front panel, the occupied space of the front panel is reduced, and the influence on the heat dissipation effect of the front panel is reduced.

When the BMC receives the target switching command, the control signal switcher disconnects the No. 2 channel, so that the signal switcher disconnects the communication connection between the host system and the front panel.
203. The BMC establishes communication connection between a first UART interface of the BMC and a first USB interface of the front panel through the GPIO/I2C bus control signal switcher according to the target switching instruction;

For example, when receiving the target switching command, the BMC controls the signal switch to connect the channel No. 1 and the channel No. 3 through the GPIO/I2C bus according to the target switching command, so that the signal switch establishes a communication connection between the first UART interface of the BMC and the first USB interface of the front panel.

Meanwhile, the BMC enables the target UART equipment to be applied to the SOL function, so that the SOL function can be realized by gating other UART serial ports through the target UART equipment, or the target UART equipment can gate a second UART interface of the intelligent serial port screen to realize interaction between the host system and the intelligent serial port screen. It should be noted that the target UART device may be a UART1 controller or a UART2 controller, or may be other UART controllers, which is not limited herein.
207. The intelligent serial port screen establishes interaction with the host system through the target UART equipment.

In addition, the interaction between the host system and the intelligent serial port screen is realized by redirecting the host system to target UART equipment under the LPC bus of the BMC and then switching the target UART equipment to the intelligent serial port screen through the BMC.
