* Compiler: KEIL C51 V6.02 *
* *
* Description: 3个中断源：定时器0-----60ms中断 *
* 串口1 -----接收卡号中断 *
* 串口0 -----与HUB联系中断 *
* 计费方式为按流量计费 *
* 2004-03-11:修改了靠卡模式 --- 靠卡消费开始 --- 撤卡消费结束 *
* 2004-03-12:判断卡信息中消费额 *
* 2004-03-15:能显示负数余额 *
* 2004-06-02:计量模式为以时间计算 *
* 2004-08-09:脱机保存数据200条消费记录 *
* 添加消费流水号(初始流水号为1) *
* 用户程序（南京化校新校区） *
* 以时间为单位收费x分/1s *
* 此程序为MIFARE卡(由M1卡读头发送序列号加检测脚) *
