In the next two days, I will be releasing three pieces of software that have been the result of years of work. All three were last updated roughly two years ago, and two out of the three may be the final versions. In order of release, the three programs are Doors CS 7.2 Beta 3, gCnClient 2.0, and Sandpaper 1.0. Doors CS 7.2 Beta 3 is final beta release of Doors CS 7.2, which brings new networking features to the popular calculator shell. gCnClient 2.0 is a final, stable version of the Windows/Linux/Mac OS software for connecting calculators to the internet. Sandpaper 1.0 is a completed FTP server and client for transferring files across a room or around the world.
This article features Doors CS 7.2 Beta 3, the latest and greatest version of the venerable Doors CS shell for TI graphing calculators. The last Doors CS beta, version 7.2 beta 3 was released one day shy of two years, the same day that Gossamer, the widely-publicized web browser for TI graphing calculators. The next version will (hopefully) be the full Doors CS 7.2, which will probably be the last release for the TI-83 Plus and TI-84 Plus line of non-color-screen graphing calculators. So what does Doors CS 7.2 Beta 3 bring? The three major changes:
Across-the-board optimizations, bug fixes, and speed improvements
Greatly-improved direct USB (miniUSB) globalCALCnet stability
BASIC CALCnet, a set of libraries within the DCSB Libs to let TI-BASIC programmers use the CALCnet networking system in their own programs.
Special thanks go to Tim "Geekboy" Keller for his hard working writing the BASIC CALCnet libraries and helping to debug and repair other CALCnet/gCn features. If you want to try making multiplayer TI-BASIC games, if you want to use direct USB CALCnet, or if you simply want the latest and greatest in Doors CS versions, you should grab this update. I particularly encourage you to report back in the attached thread whether everything worked perfectly or if you encountered errors, as I can't release the final Doors CS 7.2 update until I feel sufficiently reassured that testing has shown this beta to be stable and reliable. Enjoy, and I look forward to your feedback.
