tty

( /T·T·Y/, /tit´ee/, n.)

   The  latter pronunciation was primarily ITS, but some Unix people say
   it  this  way  as  well; this pronunciation is not considered to have
   sexual undertones.

   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.

   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.
