Dear all: I have read ci.txt under documents/dvb, and at end of it, it mentions about apdu protocol defined in en50221. but I cannot see this part of source in dvb_ca_en50221.c. Is this part implemented at other place or I check the wrong document? appreciate your help, miloody -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
