That's a way to see things :-) Jean-Luc was not talking of readers in general but of CCID readers only. A CCID reader does not use a proprietary and confidential interface but a public interface [1]. That's why Jean-Luc and myself were able to write CCID drivers for a large part of (even unknown) readers and not just one reader from one particular manufacturer. When I have the specifications of both a character-level reader and of an APDU level reader I prefer writing a driver using APDU. To take Jean-Luc example: I prefer using ATDT to dial a number on a modem than sending each correct sound modulation on the line and deal with synchronisation, etc. I think we are going off-topic :-) Regards, [1] http://www.usb.org/developers/devclass_docs/ccid_classspec_1_00a.pdf -- Dr. Ludovic Rousseau [EMAIL PROTECTED] -- Normaliser Unix c'est comme pasteuriser le camembert, L.R. -- _______________________________________________ Muscle mailing list [EMAIL PROTECTED] http://lists.musclecard.com/mailman/listinfo/muscle
