ISCardISO7816::GetResponse method
[The GetResponse method is available for use in the operating systems specified in the Requirements section. It is not available for use in Windows Server 2003 with Service Pack 1 (SP1) and later, Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The Smart Card Modules provide similar functionality.]
The GetResponse method constructs an application protocol data unit (APDU) command that transmits APDU commands (or part of an APDU command) which otherwise could not be transmitted by the available protocols.

HRESULT GetResponse(
[in] BYTE byP1,
[in] BYTE byP2,
