ChangeDirection Method
Sends a Change Direction (CD) command.
Syntax
oftpclient.changeDirection([callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This method sends a Change Direction (CD) command to the remote host when called. In normal operation this should not be used. This should only be used if a condition arises where you must manually change the speaker when communicating with the remote host.
