A mode that allows a program to transfer bits directly to or from an I/O device (or, under {bogus} operating systems that make a distinction, a disk file) without any processing, abstraction, or interpretation by the operating system. Compare {rare mode}, {cooked mode}. This is techspeak under Unix, jargon elsewhere.
