Problem with gplpcsc (PC/SC for Prolog)

I am writing an article about different PC/SC wrapper and found the
Prolog wrapper at [1].

I try to use it but can't make my sample to work. I attach my sample program.
The output I get is:
ATR: [3B FA 94 00 00 81 31 20 43 80 65 A2 01 01 01 3D 72 D6 43 21 ]
tr: 00a404000aa00000006203010c0601 - 9000, t= 14ms.
RĂ©ponse : []
SW : [144,0]
Application error in transmit APDU de test
RĂ©ponse : []
SW : [144,0]
GNU Prolog 1.3.0

I traced the APDU at the pcsc-lite level and the second APDU is not sent.
In some cases I could send the two APDU but after restarting the
program it failed again.

I am not a Prolog expert or even user. I learnt Prolog more than 10
years ago at school :-)

Can you help debug my sample?
And I have to submit my article in 2 days :-(

Thanks a lot for any help,


 Dr. Ludovic Rousseau
