Qmodem

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.

Qmodem evolved to include features such as the ability to host a simple Bulletin Board System.

An independent free software re-implementation of Qmodem for Unix-like systems called Qodem[9] started development in 2003.

Qodem is in active development and has features common to modern communications programs, such as Unicode display, and support for the telnet and ssh network protocols.
