智能卡编程，执行SCardTransmit失败。
一个读卡器，符合微软的PSCS标准
一个卡，符合通讯协议ISO同步协议,接触式卡。
连接读卡器成功，但是往里面发命令时就失败。
hCardHandle 句柄已得到。
BYTE command[256]={0x--,0x--}; //发送命令
DWORD commandLength=15; //发送命令长度
BYTE m_ReturnData[260]; //返回值
DWORD m_resultLength; //返回长度
LONG lReturn = SCardTransmit(hCardHandle, SCARD_PCI_T0, command, commandLength,
NULL, m_ReturnData, &m_resultLength);
返回错误： lReturn =87 。。
请各位大虾帮忙解决。。
