Qmodem was an MS-DOS shareware telecommunications program and terminal emulator. Qmodem was widely used to access bulletin boards in the 1980s and was well respected in the Bulletin Board System (BBS) community. Qmodem was also known as Qmodem SST and Qmodem Pro.
History
Qmodem was developed by John Friel III in 1984 and sold as shareware through a company called The Forbin Project. Qmodem gained in popularity very quickly because it was much faster and had many new features compared to PC-Talk, the dominant shareware IBM PC communications program of that time.
Originally developed in Borland Turbo Pascal, the application originally supported the XMODEM protocol, gradually added support for other protocols such as the popular ZMODEM protocol and CompuServe-specific protocols such as CIS-B and CIS-B+. Qmodem evolved to include features such as the ability to host a simple Bulletin Board System. The application was sold to Mustang Software in 1991 and in 1992 version 5 of the program was released.{{cite news
