The ''' Terminal Interface Unit''' (usually referred to by the acronym, '''TIU''') was a software package created by [[SRI International|SRI]] which ran on a [[PDP-11]] and allowed a number of [[user]]s at [[terminal]]s to connect to [[time-sharing]] [[host]]s over the nascent prototype [[Internet]], using [[Telnet|TELNET]] over [[TCP/IP]]. It was initially targeted at use over the prototype [[Packet Radio Network]], but was later adapted to operate attached to the [[ARPANET]].

It is historically important, as one of the very earliest TCP/IP implementations (although its origins date back to before the separation of [[Transmission Control Protocol|TCP]] and [[Internet Protocol|IP]] into separate [[protocol]]s). It was one of 6 prototype implementations of TCP/IP tested at the ground-breaking 'TCP Bakeoff' held at [[ISI]] on 27 January, 1979 (likely the very earliest attempt to get different TCP implementations to connect to each other), along with:

* [[UNIX Sixth Edition]] from [[Bolt, Beranek, and Newman|BBN]] in [[MACRO-11]] (itself a [[software port|port]] of the TIU implementation)
* UNIX Sixth Edition from BBN in [[C programming language|C]]
* [[TENEX]] for the [[PDP-10]] from BBN
* [[OS/360|OS/MVT]] for the [[IBM System/360|IBM 360]] from UCLA
* [[Multics]] from the [[MIT Laboratory for Computer Science]]

It was was written in MACRO-11, and ran on the [[MOS operating system‎]] (created at the time of the TIU work). The code and documentation have been saved (see links below).

It was initially able to connect to networks which used the [[1822 interface]], using the [[Stanford 1822 Interface‎]], and later the the [[Advanced Computer Communications|ACC]] [[MLH-DH/LSI11 Multiple Channel Controller|MLH-DH/LSI11]].
