9、elect()三个函数），成功可返回卡的序列号。（4）（5）用 rf_anthetication() 函数验证设备和卡中，一次只能验证一个扇区。对已验证过的扇区可进行读、写、初始化值、加值、减值等功能操作。对其它扇区的读、写操作必须重复上述（4）过程。（6）（7）（8）由于高级函数集成了若干低级函数，所以调用前可不必运行（3）、（4）过程。对某操作完成后，应用 rf_halt()函数中止对该卡的操作。程序正常退出或因错误退出之前，要用 rf_exit()函数关闭串口；否则，因为串口被占用，再次执行初始化串口时将出错。（9）ML 卡有的三个函数 rf_init_ml()、rf_decrement

10、_ml()和 rf_readval_ml；减值以后，再Page 6 of 69次对卡操作（包括读值）时须重新寻卡。（10） 有关调用各种函数库的具体方法，请参考:Exles目录下的使用范例。4库函数简介本手册主要描述了 RF 系列的 API 函数，包括通用函数、设备操作函数和卡片操作函数。对于不同的操作系统，函数的参数和返回值的数据类型是不同的，并且有些函数是没有的。Flow Diagram of the Operations on RF series4.1 通用函数简介通用函数用来实现打开/关闭串口、加密/换等。Windows 函数:usb_init();以及16进制字符串和 ASCII 字
