What is the X in X-mas?
The normalUnix character-input mode, with interrupts enabled and with erase, kill and other special-character interpretations performed directly by the tty driver. Opposite of raw mode. See also rare mode. Other operating systems often have similar mode distinctions, and the raw/rare/cooked way of describing them has spread widely along with the C language and other Unix exports. Most generally, "cooked mode" may refer to any mode of a system that does extensive preprocessing before presenting data to a program.
