* The Elektor DRM Receiver 3/04 COM interface is based on the Visual Basic

* Linux support is based on a code written by Markus M<>rz:
* http://mitglied.lycos.de/markusmaerz/drm
* Linux support is available from DRM Dream project.
*
* The DDS is a AD9835.
*
* The receiver is controlled via the TX, RTS and DTR pins of the serial port.
