[Muscle] newbie: How to send a APDU packet over T=1 protocol

[harishankkar]

Hi all, I am using an infineon smart card which works only over T=1 protocol. I tried sending an APDU packet to the smart card using T=1 protocol after getting ATR.  I tried the following sequence 0x00, 0x00, LEN, CLA,INS,P1,P2,0x00,LRC.  The CLA, INS, P1, P2  are respectively 0x00, 0xCA, 0x01, 0x82(This is the GET DATA command in Card OS and I m using 0x82 to get the OS version) . I am not getting any responsse from the smart card. Where am I going wrong? I am a newbie to smart cards and I dunno much about this. Is my sequence right??   Harishankkar
