How to save short messages to the computer?

When the mobile phone is turned on and connected to the computer, select the serial port. After Unicom, you can see the information in the mobile phone in the short message bar, and then you can select all, or select short messages and press ctrl+a to select all, copy or export short messages (I usually export them, and the exported files can be opened in EXCEL). You can take a closer look at the options and the operation is relatively simple. I won't go into details, but I don't really remember. Hehe, forgive me
