功能描述：获取数据,CosBuf[5]={0x00/04,0xb0,0x80+namel,offset,le};。 
输入条件：SysKind=0--->EasmChip的操作，SysKind=1-->CpuCard的操作,FileId二进制文件标识符,Length:要读取的长度
输出项目：RetData=0x00操作成功;RetData=0xFF此操作失败。

unsigned char ReadBinary(bool SysKind,unsigned char FileId, unsigned char OffSet, unsigned char Length)
{
    unsigned char i;
    CmdBuf[CLA] = 0x00;
    CmdBuf[INS] = 0xb0;
    CmdBuf[P01] = 0x80 + FileId;
    CmdBuf[P02] = OffSet;
    CmdBuf[P03] = Length;
    for(i = 0; i < 3; i ++)
    {
        CosCommand(SysKind,3,Length);
        if( (SwBuf[0] == 0x90) && (SwBuf[1] == 0x00) )
        {
            break;
        }
    }
    if(i < 3) 
    {
        return 0x00;
    }
    else 
    {
        return 0xff; 
    }
}
