OnSend is a TIdFSPLogEvent property that represents the event handler signalled after an FSP packet is sent. OnSend is signalled when methods in the client that implement the commands in an FSP protocol exchange are called. 

Arguments to the OnSend event handler indicate the object instance for the notification and the TIdFSPPacket instance written during the FSP protocol exchange. 

Use the OnWork, OnWorkBegin, and OnWorkEnd event handlers to respond to events signalled when retrieving the content of a file using the Get method.
