Referring to fig. 1, fig. 1 is a diagram illustrating an embodiment of a method for interaction between an intelligent serial port screen and a BMC, 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. Or, the BMC may also receive a target handover 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. Therefore, the communication connection between the first UART interface of the BMC and the first USB interface of the front panel is established according to the signal channel switching. For example, when the signal switch is a multi-phase channel signal switch including at least channels 1, 2, and 3, the first UART interface of the BMC may be configured to connect to channel 1, and the first USB interface of the front panel may be configured to connect to channel 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 the channel 1 is communicated with the channel 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 the movable mounting buckle, for example, the intelligent serial port screen can be mounted in front of the front panel, or the intelligent serial port screen 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 are in communication connection through a second UART interface and a second USB interface, and specifically, the second UART interface of the intelligent serial port screen is connected with the second USB interface of the front panel through a UART-to-USB cable, so that the communication connection of the intelligent serial port screen and the front panel is established.
104. 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 first UART interface of the BMC is in communication connection with the first USB interface of the front panel and the second USB interface of the front panel is in communication connection with the second UART interface of the intelligent serial port screen, 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. And then, the intelligent serial port screen is in communication connection with the BMC according to the target authentication handshake protocol, so that interaction between the intelligent serial port screen and the BMC is established. Specifically, the target authentication handshake protocol may be a response handshake protocol, for example, first, a handshake encryption key of the current BMC is input into the smart serial port screen, and after the BMC control signal switch switches signal channels to complete connection from the second USB interface of the smart serial port screen to the first UART interface of the BMC, an encrypted handshake code is sent to the first UART interface.

Therefore, when information is required to be acquired interactively with the BMC, the intelligent serial port screen is not required to be embedded into the front panel and 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.
