It is always funny to answer my own questions. But the previous problem I addressed is easily solved with lock() and unlock() methods.

In fact I would like to explain a bit more.
The flowgraph consists of rx and tx path:

WBX daughterboard -------> RX path
TX path --------> LFTX daughterboard

I have random source inside tx path. I want to set a number of bits that will be produced, then run TX path and record received symbols in RX path.
When I set a certain number of bits inside TX path, after the bits are generated, TX path doesn't have anything to do and should stop. So my question is how to rerun it again.

Hello again guys,

in my applicatoin I have two flow graphs, namely, rx and tx paths, separated.
TX path generates pseudorandom bit sequence which is then turned into digital signal and transmitted over LFTX board. This signal is fed into signal generator in order to modulate FKS signal. Modulated signal is fed back to WBX board, and the idea is to measure BER.
I want now to be able to restart TX and RX paths. If i Call lock() and unlock() will flowgraph be restarted?
