* These sequences are not generated by the VT52. † In numeric keypad mode (application keypad mode off), ENTER generates the same characters as RETURN. You can change the RETURN character code with the line feed/new line feature. When off, this feature causes the key to generate a single control character (CR, octal 015). When on, this feature causes the key to generate two characters (CR, octal 015 and LF, octal 012).
