History

After using FreeHost3270 for more than a year, struggling to build the type of components, interaction models, and dealing with cruft-based race conditions from a fragile and brain-dead threading model, I decided it was time to cure my problems. A clean break in API, clean separation of concerns (leading to a clean implementation) for telnet Option extensions, and application of MVC to the terminal buffer was essential. The pile of hap-hazzardly thrown-together telnet code and the nasty Tn3270Parser, as well as the brain-dead buffer handling made me decide that a Fork wasn't going to save FreeHost3270. It was time for a fresh start, synthesized from specs and practical experience.

And thus, JinTn3270 was conceived.
