I'm developing an aplication using Microsoft Visual studio 6.0 (VC and VB) and the eMMbeded visual tools 3.0 for PocketPC. A have a PCMCIA Smartcard Reader/Writer (ACS ACR90) that works perfectly in both systems (PC and PocketPc - i've used downloaded programs with no problems).
I'm an experienced developer in other areas and other types of harware:
- Magnetic cards.
- PCMCIA.
- Etc.
But i'm a begginer in smart cards.
I've been using ScardTRansmit to send/receive data to/from the SIM card.
I can send some commands and receive the styatus response:
90 00 or 9F xx (Where xx is the number of bytes to get with GET RESPONSE).
I can't get this bytes.
I do This:
Send a SELECT command: A0A40000027F20 - Select the DFGSM
Response: 9F 22 - OK 22 bytes to get...
Send a GET RESPONSE command: A0C0000022 - Get 22 Bytes response
Response: 90 00 - OK...
Where are the response bytes?????
Can some one show me an exmple of how to use ScardTransmit to get this bytes???
Thank you.
