Connect is a virtual procedure used to open a connection to the PeerIP and PeerPort using the socket handle for the descriptor. Connect uses the GStack global protocol stack to connect the socket handle to the remote system. 

Connect calls UpdateBindingLocal and UpdateBindingPeer to reflect the real IP address and Port numbers used for the connection when the socket handle is allocated. This operation is thread-safe; it is protected by an internal TIdCriticalSection instance. 

Use CloseSocket to close and destroy the socket handle.
