It can be appreciated that the complex editable logic device may implement the UART serial port switching operation.

Step S12: and acquiring the target UART signal output by the complex editable logic device, and converting the target UART signal into a corresponding USB signal by utilizing a preset UART-USB conversion chip.

In this embodiment, after the management board obtains the target UART signal output by the complex editable logic, the target UART signal is converted into a corresponding USB (Universal Serial Bus, i.e., universal serial bus) signal by using a preset UART-USB conversion chip. It can be understood that, in the embodiment of the present application, a uart_usb conversion chip is added to the management board card, so as to convert UART signals into USB signals, thereby implementing a function that the serial port transmits with a USB interface.

Step S13: and outputting the USB signal to a target terminal through a USB interface on the management board card.

That is, the target UART serial port corresponding to the first class of UART signals is a first UART serial port, the target UART serial port corresponding to the second class of UART signals is a second UART serial port, and the corresponding UART serial port is used as the target UART serial port according to the signal type of the UART signals, so that the target UART serial port is used as the current UART serial port of the complex editable logic device. For example, if the baseboard management controller outputs a first UART signal, the first UART serial port is used as a target UART serial port, as shown in fig. 3, and the first UART signal is subjected to subsequent processing by the management board 1; if the baseboard management controller outputs the second UART signal, the second UART serial is used as the target UART serial, as shown in FIG. 3, and the second UART signal is processed by the management board 0.
