Function Documentation

PHSetProtocol()

DWORD PHSetProtocol	(	struct ReaderContext *	rContext,
		DWORD	dwPreferred,
		UCHAR	ucAvailable,
		UCHAR	ucDefault )

Determine which protocol to use.

SCardConnect has a DWORD dwPreferredProtocols that is a bitmask of what protocols to use. Basically, if T=N where N is not zero will be used first if it is available in ucAvailable. Otherwise it will always default to T=0.

IFDSetPTS() is always called so that the driver can initialise its data
