I'm using SecureBlackbox Product Version 10.0.233.0 for VB.NET

The TElSimpleFTPSClient.Close(True) method passes True to the 'Silent' variable which means the method executes a non-graceful closure. What is the difference between a graceful closure and a non-graceful closure? Specifically, I'm interested in whether or not the FTP "quit" command is issued before closing the connection during a non-graceful closure.

Is there a way to log which FTP commands are being issued via a method or property in Secure Blackbox?

I have updated my support access ticket to my user account. Thank you for your assistance with this.

Some additional information concerning this issue:

We are uploading files to a clients FTP site (using TElSimpleFTPSClient.UploadFile()), and they claim we are closing the connection before issuing a "quit" command in FTP. This is causing an error (on their end) in the last file that we send them.

No, QUIT command is not sent in case Silent parameter is set to true.

Yes, you need to handle OnControlSend and OnControlReceive events.

Please note that you have a license with lifetime free upgrades and it makes sense to upgrade your version of SecureBlackbox to version 14, as the latter includes numerous improvements including complete TLS 1.2 support, SHA2 cipher suites and more.
