/tit'ee/ (ITS pronunciation, but some Unix people say it this way as well; this pronunciation is not considered to have sexual undertones), /T T Y/ 1. teletypewriter. 2. (Especially Unix) Any terminal at all; sometimes used to refer to the particular terminal controlling a given job (it is also the name of a Unix command which outputs the name of the current controlling terminal). 3. (Unix) Any serial port, whether or not the device connected to it is a terminal; so called because under Unix such devices have names of the form tty*. Ambiguity between senses 2 and 3 is common but seldom bothersome. 4. A TDD.
