Hello,
I am trying to send a response apdu command using the T=0 protocol. I can send back a simple response apud (0x90 0x00) but I get a failure when attempting to transmit data. The command header is (hex) 90 CA 01 01 20 (a get data request). My response is 32 bytes of data and sw1 / sw2.

I am using the Raisonance emulator and a GemPlus reader. The host application is using the PC/SC smartcard api.

Any help would be appreciated,
Thanks, Alan
