    SectionR using the ■V TIO O -128 Terminal Emulator WHAT IS A TERMINAL EMULATOR? Many large computers, aswell as some information services, recog­ nize special escape sequences to cursor-up, cursor-down, clear the screen and perform other screen editing functions. These escape sequences allow the computer to display the screen much faster than if every space and character had to be printed, and scrolling occurred line by line.
