There does not exist such an event.

There are two similar named events, OnDataSent and OnSendData.

OnDataSent triggers after ALL data buffered in TWSocket's
internal send buffer has been actually sent by winsock API send().

And there is OnSendData that triggers whenever data has been
sent by winsock API send().

Whenever you call one of TWSocket's send-methods data is copied
to TWSocket's send buffer first and the component the sends it
asynchronously in the background.

No, see above. Winsock does not provide such a callback or event.
