I believe citi.umich.edu has some example code in their sc7816 tar file that creates
files. The xcard example found in www.linuxnet.com shows it for program file.
Anyway, to decypher it, you need to ignore all "," (commas) and see that the first 5
bytes are APDU commands.
0x10 (5th byte) means that 16 bytes of data follows.
The 16 bytes are the various fields needed to create a file. To read the details on
each of the field, you need to look at various tables found on pages 155-58
(SelectFile command).
If you get our Windows kit, you can see the actual APDUs being used to create the
various file types. I don't have the tool handy to do so. Sorry.
We'll be releasing a more accurate and usable documentation in few weeks. Keep
checking www.cyberflex.slb.com.....
Good luck,
Danny
