Will it disconnect the data channel, the command channel or both?

That is based on the presumption that you can close the existing 
connection. I don't know anything about the implementation 
details of FTP in CF, but on the TCP layer just closing the 
connection can already take up to 4 minutes.

If closing fails, you can't reopen it.

Start a brand new connection whenever you are disconnected and 
use that until you are disconnected again.
