How do I change values in Rhinoscript in Rhino 3D?

Question

I am using a script in Rhino to import files and and export them to AutoCAD .dxf-files. Before I export I want to change the Export Scheme option to R12 Natural or Default.

I am using the following code line to open the AcadScheme dialog window:

Rhino.Command "_AcadSchemes ", 0

But how do I change the value inside the Export Scheme box?

I tried adding things like "_ExportScheme=Default " or "ExportScheme=Default " but apparently this doesn't work. I know it's probably wrong syntax.

Does anyone know how to alter these values? I can't gather any useful information from Google or the Rhino Help.

Ok this is in case someone runs into the same issue as I did. So I contacted one of the developers and I received this answer:

[...] As I said, you can't access the individual settings via the command line. [...] The "Import" function in the DWG/DXF options dialog does not appear to be scriptable currently either.... --Mitch
