Well it has been some time and an update was overdue. Anyways thanks to the help of Günter Khyo the rxd device driver was update for kernels 2.6.28 and later. You can get additional information to this educational project at the rxd Sourceforge page. There also exists a project wiki and you can view the source code across all available versions (0.1.1 and 0.2) in the project’s CVS repository.
