== IBus Gateway ==
OpenBM-Gateway is a linux daemon running in the background and acting as a gateway between BMW's IBus and the D-Bus. In this case an IBus interface is connected to the PC's serial port. The interface must support CTS line. Hence some hardware collision detection, or at least a simple bit comparator must be implemented. This function is provided for example by the [http://www1.futureelectronics.com/doc/MELEXIS/TH3122.4+KDF-TU.pdf TH3122] ic, which I am also using in this project.

[http://www.freedesktop.org/wiki/Software/dbus D-Bus] is an interprocess communication message system. Any other application can connect to D-Bus in order to communicate with the OpenBM gateway. Messages received over IBus are transferred to D-Bus and vice versa.
