Sorry, Richard. I don't have a good answer. I tried here, and things  
worked as expected.

-- Unplugged during the transfer, and get a socketTimeout.

-- Tried again while still unplugged, and get a "Can't connect to  
host" error.

-- Plug in again, and the transfer takes place with no problems.

The 550 error looks like an FTP error, usually for "file not found"  
or "no access to file/folder". But I wouldn't expect it when  
uploading. You usually this when downloading non-existent files or  
files with the wrong permissions.

I guess the consequeces of pulling the cable may vary from network to  
network.

Also, there may be differences between FTP servers about how they  
behave when a transfer is interrupted. I tested with pure-FTP server  
on OS X.
