With the ISO 7816-3 T=0 protocol, you CANNOT send directly APDU case 4 which is sending some data and receiving back some data (CLA INS P1 P2 Lc Data1 Le and the answer is Data2 SW1 SW2) with only ONE command. This is not possible. Christophe Colas Bull Smart Cards & Terminals Phone: 33 1 39 66 42 29 Fax: 33 1 39 66 43 51 mailto:[EMAIL PROTECTED] Visit us at http://www.cp8.bull.net.

Okay, I see the point about making the CardTerminals independant of how the card handles the case 4 APDU, but it seams that everybody asumes that the T=0 protocol needs to split APDU's into this scheme of first sending the command and then retrieving a 61xx response and then sending a getResponse APDU, that is offcourse NOT the case some cards can perfectly well handle case 4 APDU's in one go using the T=0 protocol. The most important thing to do is once and for all to make a decision about the correct CardTerminal behaviour, and even though it means some extra work for myself, as I have implemented a CardTerminal. I thing that hiding the 61xx/6Cxx stuff from the CardService is the most sensible. -- S�ren Visit the OpenCard Framework's WWW site at http://www.opencard.org/ for access to documentation, code, presentations, and OCF announcements. --------------------------------------------------------------------------- -- To unsubscribe from the OCF Mailing list, send a mail to "[EMAIL PROTECTED]" with the word "unsubscribe" in the BODY of the message.
