The DCLRail program is a result of a project dealing
non-functional properties of embedded systems at
Systems Engineering, University of Potsdam, Germany.
The project includes a library that allows controlling and monitoring
Märklin Digital model railroad. Special attention has been paid in
implementation to achieve low reaction times.
Based on this library, a shell allows interactive control and execution
of shell scripts.
In addition to that a QNX image is provided wich fits on a floppy
and allows using the software without any unneccessary overhead of
graphical user interface.
A paper describing architecture and technical details is going to be
published as technical report by the Hasso-Plattner-Institute.
