Telix is a telecommunications program originally written for DOS by Colin Sampaleanu and released in 1986. More recent versions were distributed by deltaComm Development, including a version for Windows.
The DOS version was considered by some to be one of the most popular shareware programs of the late 1980s and early 1990s. Its strengths included having a fast version of Zmodem built-in, rather than needing a separate program, and a powerful programming language, 'Salt'.
The Windows version suffered from a variety of problems, including delays in publication (it was a complete rewrite by a new author in Turbo Pascal for Windows rather than the original's C), an unpopular attempt at copy protection and the World Wide Web's impact on bulletin board systems also reduced demand.
Telix can be used to dial bulletin board systems or other phone-line based services. It supports ANSI emulation and various file transfer protocols.
