// To be able to use the BssCfgManip COM object as shown:
// - Right click on C# project, Add > Reference..., COM > Type Libraries, BssCfg915Lib
// - Replace "915" with the actual BssCfgManip version for your SSH Server installation, both in Add > Reference, and in this code
// - BssCfgManip version does not increment if there are no changes, so e.g. BssCfg915 applies to 9.xx versions 9.16 and higher
