Set the TERM environment variable to the terminal. VT100 and vt220 here indicate the simulation product type. The terminal is a very important peripheral. People who have used the terminal equipment know that if the device type is incorrect, there will be chaotic characters. You can also use the simulation terminal software such as netterm to test it, linux terminal information is stored in/usr/share/terminfo. Many subdirectories such as VT100, vt102
