So in fact here the code in "Pcsc10CardTerminal" sets the 'le'
local variable to apduCommand[4] and then tries to identify in
which ISO case we are. If it's case 4, this variable does not
indeed contain Le but Lc :-(, the 'le' variable is then redefined
to apduCommand[apduCommand.length - 1]. What does that mean? It means
that you are (or an application) trying to send an APDU to the card
that is a Case 4 but do not seem to fulfill the ISO requirements
(i.e., you should have 4 bytes, then Lc, then data, and at the end,
Le and -the most important- Lc should be the total length of the
buffer (85?)-5-1=79 which does not seem to be the case..).
I'm not a good specialist in T=0 but I believe the code is right..
Could you send us the APDU you are trying to send to the card ?
(in hexa) by using the trace facility (settings in the
opencard.properties file) ? That would help. And if I don't see
I will get back to the T=0 experts I know (thanks Thierry! :-).

If you are using any type of serial reader, you can use the pure
java driver and have no more need for PC/SC ;-), you will find the
pure java CardTerminal at:
http://www.gemplus.fr/developers/technologies/opencard/cardterminals/download.html
and if you are using GPK, you will find the relevant CardServices at:
http://www.gemplus.fr/developers/technologies/opencard/cardservices/download.html
Hope it'll help.
Cheers,
Christophe.
