 A notable exception was DOS and older versions of the Win32 console of Microsoft Windows.Almost all manufacturers of video terminals added vendor-specific escape sequences to perform operations such as placing the cursor at arbitrary positions on the screen.One example is the VT52 terminal, which allowed the cursor to be placed at an x,y location on the screen by sending the character, a character, and then two characters representing with numerical values equal to the x,y location plus 32 (thus starting at the ASCII space character and avoiding the control characters).
