摘　　要：基于TCP/IP的网络普遍存在各种安全问题,对于安全级别较高的单位,采用物理隔断的方式又带来了成本增加和数据难以共享等问题。要解决这一问题,可以通过在物理隔断网络之间采用串口连接的方式进行通信,具体的方式是:通过串口连接两个物理网络,两个网络中,如果需要与对方网络进行通信,则将数据按着本设计要求将数据发送给本网串口连接程序,该程序会自动将数据由串口传送给对方网络串口连接程序,而对方程序可以将数据按要求再转送给该网络中指定的用户,从而实现了实时通信。通过测试验证,该方式可以传送文件、实时数据、网络数据包等多种形式,并且设计可行和有效。There are many security issues on TCP/IP network, for some companies which need high-level security, they prefer to a- dopt mode of physical-isolation network, however this will increased costs and difficult for sharing data. To solve this problem, a serial port between two networks can be deployed, and all the data pass through this serial port. That is to say, there are two speci- fied serial program software at both sides of this serial port. If a software program A in one network want send data to another soft- ware program B in another network, the program A can send data to this serial program, and then this serial program will send these data to another network by serial port. In opposite network, another serial program will receive these data, and then send them to the software program B in that network. Through the test for verification, this method can send files, real-time data, and so on. This proves the method is feasible and effective.
