调试串口设备时候接收到客户端发送特定数据时，需要本机回传另一个特定字符串。因为网上不好找到具有类似功能的软件，所以自己写了一个。可以实现接收串口数据，单次发送，连续发送，接收特定数据后发送的功能。可以接收、显示、发送十六进制或者ascii。缺点是串口没有采用Overlapped方式，发送数据的时候会有点慢。另外软件的应用上面也有点不够人性化。拟改进。-Debugging serial devices to the client when receiving the data sent when a specific need to return the machine to another specified string. Because of the Internet to find good software with similar functions, so to write one. Can be achieved to receive serial data, a single send, for send, receive data sent by a particular function. Can receive, display, send or hexadecimal ascii. The disadvantage is that the serial did not use Overlapped way to send data when a bit slow. In addition the application software not above a little humanity. To be improved.
