I might add that the solution was created a long time ago when the
concept of using components to be dropped on datamodules was what we
However, this dongle component can equally well be used without being
dropped anywhere, it is just another class really.
I would not have a problem using it as a general purpose object and
changing my programs accordingly, that would be pretty easy, provided
I can make it work in Lazarus/FPC.
