The Extended ASCII chart below illustrates the details of the codes. Together with the control codes (0 to 31) in Standard ASCII table, Extended ASCII codes are also widely used in communication protocol, such as RS-232, RS-485, RS-422 and TTL systems. As the name suggests, we can use the banner command to show text banners in the terminal. In this tutorial, we’ll have fun exploring different ways to render ASCII artwork on the terminal.
