This article details the release of the complete source code for QModem 4.51, a widely-used MS-DOS telecommunications program from the early 1990s authored by John Friel III. The code, built using Turbo Pascal 5.5/6.0 and potentially Turbo Professional libraries, is offered for historical study, restoration, and educational purposes. QMODEM was a robust program supporting numerous modem speeds, file transfer protocols, scripting, and even a built-in BBS-like Host Mode. The repository includes the full source code, build scripts, and instructions for attempting to rebuild the program, acknowledging that direct porting to modern environments is highly experimental and requires careful attention to the original MS-DOS-specific conventions and overlay management system. The project’s reliance on direct hardware access and third-party libraries further complicates any modernization efforts.
