Remarks:

For scanners that implement IG_ISIS_TAG_SCANTYPE, your application can control the source of the scan. For other scanners, most will scan as though this tag is set to IG_ISIS_TAG_SCANTYPE_AUTOMATIC. You can query the choices of this tag to determine the capabilities of the currently-selected scanner.
