    0x85 01 5a a5 command to download specified files, you can download all kinds of files to the serial port screen via serial port, including pictures, fonts, voice, video and other kinds of files. If the customer’s motherboard can be connected to the network, this function can be used to remotely update some of the display contents. This command cannot be used to update the firmware of the serial panel. Downloading a file using the serial port while connected to a USB cable will cause a file error.
