[Boost-users] Suggestion about using Signals2

Hi, I need some help on using signals2 in my app, I hope to explain my problem well. I have a thread that reads from the RS232: void SerialPort::reading() { ... read... if (data_available) signal_OnData; } the signal_OnData is: typedef boost::signals2::signal<void ()> _signal_void; _signal_void signal_OnData; And I connect it to a method MyUserClass::OnDataReceived() Into this method (MyUserClass::OnDataReceived) I need to re-send some data to RS232, but the SerialPort::reading thread is locked because it's waiting the OnDataReceived ends.. In fact, when the methods OnDataReceived ends, I receive data again. How can I solve this problem? Thanks in advance! Daniele.
