Use non-blocking mode. Switch the socket to non-blocking mode
and SSL_connect() will return with _WANT_READ in the case described.
Your application can than select() on the socket and call SSL_connect()
again, when data are available. If not, your application can SSL_free()
and close the socket, when a timeout condition was encountered.
