For those of you that are interested, I could use some help...
I have a branch of the QnetGateway github repository called "dplus" that contains what I believe to be the proper way to authorize on the closed-source DPlus system. It's not working for me, but I think there is a problem with my callsign registration. Another user tried it, and it seemed to work for him.
If you are interested, please try this branch and respond back to this thread with you findings. To use this branch, go to your build directory, uninstall your working version, do a "git pull" and a "make clean" and then a "git checkout dplus". Then you should be able to make and install this new branch. To switch back to the master branch, first, uninstall your dplus version, do a "make clean" and then do a "git checkout master" and then do a make and install to reinstall the release version.
If you "alpha testers" report that it is working, I will add some new configure variables so that you can more finely control how the authorization is done and merge that into the master branch.
Thanks for your help.
