Telix Salt Script Application Language script source
File type category:
Source code and script file
Date updated: August 9, 2013
The SLT file extension was also used by Telix for one of its file formats. Telix was 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 built-in version of the Zmodem file transfer protocol, rather than needing a separate program, and a powerful scripting programming language similar to C, 'SALT' (Script Application Language for Telix).
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.
