TTY

[UNIX | ITS, but some UNIX people say it this way as well; this pronunciation is not considered to have sexual undertones]

n. 1. A terminal of the teletype variety, characterized by a noisy mechanical printer, a very limited character set, and poor print quality. Usage: antiquated (like the TTYs themselves).

See also bit-paired keyboard.

2. [especially UNIX] Any terminal at all; sometimes used to refer to the particular terminal controlling a given job.
