Hi Denis, I have mixed some stuff concerning GIOChannels...

The set_close_on_unref() from gatutil.c is done for ppp_net interface GIOChannel. It has nothing to do with the physical layer. However, we do also: - set_close_on_unref(TRUE) into example/emulator.c - set_close_on_unref(FALSE) into plugins/dun_gw.c So after the client send ATH0, the connection is removed and emulator should be unregistered and removed but it is not the case. > In the case the PPP session is ended normally, we call > ppp_ipcp_down_notify() to free the ppp_net interface. > Then the physical layer is removed and we got the emulator well > unregistered. That's why I assume unregistration of the emulator is bound to the way PPP session is ended e.g. normally ---> ppp_ipcpdown_notify() forced ---> ATH0 > Do you have any idea about what is happening there? > Maybe I forgot to do something into dun_ath_cb().
