FTP Uncommon Compatibility Options

Demonstrates the UncommonOptions property, a comma-separated list of compatibility options for uncommon platform or server requirements. The default is empty and should normally remain empty.

Background: This is a catch-all for narrow workarounds that do not warrant their own properties — behaviors needed only by a particular server or platform quirk. Most applications never set it. When you do, it is to satisfy a specific documented requirement, and the exact keyword matters, so consult the reference list rather than guessing.
