Public Function ClearCommandChannelAsync ( _

) As Task
public Task ClearCommandChannelAsync(
	Object state


Type: System..::..Object
An optional user-provided object that identifies this particular asynchronous operation.


Implements the FTP CCC (Clear Command Channel) command.

This command is used in circumstances where it is desirable to protect the control connection only during authentication, when user credentials are being sent by the client.

When the control connection is reverted to plaintext, subsequent data transfers will be protected with the current SecureTransfers settings.
