I have completed the project. Deliverable consists of the entire TCPIP "Demo App" zipped into one folder, guaranteed to compile and likely to run on your hardware. This includes printing a variable to the website. Will provide basic support, but additional modifications will require a new proposal.
I have written this using a best practice modular approach. You will find minimal changes to main.c. Instead, there are two new files in the project (not sure on names right now): DeviceCtrl.c and DeviceCtrl.h. Use a file compare utility, such as WinMerge to compare changes between the base project and my changes.
FYI: The project file was written in MPLab 1.90 and may not be backwards compatible. I had some issues with 1.90, so if you aren't using it, I don't recommend upgrading. Instead, I would add the changed files to your existing project.
