Sample working Script that uses FEAT and certificates

Hi, Does anyone have any sample scripts that allow connection to an FTP site that requires FEAT to be enabled, and access is controlled by a private certificate.
 
I can access the site using the GUI, but the sample scripts provided on the site don't show me how i can set the enumeration for the FEAT command,  So any help on how to set the FEAT command etc preferably in powershell or VB would be a great start.
 
Thanks
 
Tim

The powershell script is available here:
