为调试设备编写的RS232转以太网通信软件。 均使用异步通信方式，RS232使用API编写，以太网使用Sockte类。程序中使用了两个独立线程，线程间以消息方式传递数据，本程序中包括：RS232异步通信、Sockte异步通信、用户界面线程、线程间通信。-Equipment prepared for debugging RS232 to Ethernet communications software. Only use asynchronous communication mode, RS232 using the API written in Ethernet using Sockte class. The program uses two separate threads, the threads in the message is transmitted data, this program includes: RS232 asynchronous communication, Sockte asynchronous communication, the user interface thread, communication between threads.
