Hi, all I start up pppd over a mux channel, and it can work well. And I also implement the method requestDeactiveDataCall() of RIL_REQUEST_DEACTIVATE_DATA_CALL request in ril. In requestDeactiveDataCall() function, I stop the pppd by setting a property which is define in init.rc. Pppd receives the SIGTERM signal. After pppd exited, I want to make mux data channel to switch to command mode by send AT command "+++". However, the data channel cannot be writen, it returns "Try again".
