Sends CCC (Clear Command Channel) command to the server.

Object Oriented Interface

public function doClearCommandChannel($gracefulsslclosure);

Procedural Interface

secureblackboxlite_ftpclient_do_clearcommandchannel($res, $gracefulsslclosure);

Remarks

Use this method to send a CCC command. CCC clears command channel encryption state, turning off TLS encryption.

Some servers expect this command to allow for the control channel to be properly handled by NATs.
