前言

CatSerialServer是一个跨平台串口通信服务进程，或许有疑问为什么串口通信要用独立进程放在客户端主进程上不好吗，也不是不可以而是在windows系统会有点问题，如果你客户端UI主程序程序用了windows原生边框，以及去掉了边框而去边框的底层实现是使用了windows原生的API，重写nativeEvent，这些方式在界面拖到改变大小的时候都会阻塞了串口底层数据收发，考虑过多种方式解决该问题，最后考虑使用多进程方式解决。

软件架构

使用Qt RemoteObjects作为进程间通信方式之一，使用IPC实现本机间进程通信
使用 QWebSocket 作为进程间通信方式之一，实现跨进程，与跨设备通信，只要支持websocket的应用都可对接该服务

功能需求

服务端功能

支持串口热插拔
获取串口列表
打开，关闭串口设备
获取当前打开的串口设备
打开成功，打开失败，串口占用，断开连接API接口
发送和接收数据API接口
websocket实现json格式api
同时支持windows，linux，mac
同时支持 mingw，msvc，gcc等
config配置可配置pid，vid过滤

客户端SDK

使用Qt RemoteObjects实现进程间通信，需要配合服务端的Qt RemoteObjects接口
使用 WebSocket实现网络通信接口。

服务端ini配置

//SerialServerConfig.ini
[General]
WebSocketServer_Port=10024
// 配置串口需要过滤的pid，vid
[SerialFilter_Pid_Vid]
1\0="11111,0000"
2\1="11112,0000"
size=2
