tty
<hardware> /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.
