SCardTransmit and T=1 Protocol

[daleh@hill-eng.com]

All,
I'm trying to understand the SCardTransmit Windows API. The documentation is clear on sending T=0 APDUs but not so much for sending T=1 APDUs. From looking at examples it would appear that you format the header for T=0 even if you are sending T=1 APDUs -- is this correct?

TIA,
Dale

I don't know details, but a quick search pointed to using SCARD_PCI_T1, see http://osdir.com/ml/lib.muscle/2004-12/msg00012.html
