Receives incomming data until waitingTerminate returns true. Input buffer is not cleared, incomming bytes are appended to the input buffer content,
so the method can be called multiple times. If some data were received in the meantime and waitingTerminate returns true for that data, method returns immediately
to process returned data. Method waitingTerminate checks always whole receive buffer. Before call of WaitForwithoutSend, waiting must be initialized
by calling BeginWaiting wich sets up timeout-check events.
