how does a TCP client handle async connect ?

[piersh-aetheros]

i'm trying to work out how to get a COSEMClientEngine-derived class to handle the async connection event of a TCPWrapper transport, but I don't see any mechanism by which that is exposed by COSEMClient.

the ClientApp example shows calling m_pSocket->Open(), and then m_pClientEngine->Open() as separate commands, but I need to be able to link the two automatically when the connection opens.
