解决方案三：
问题现象是：向串口发送数据后，串口无回答数据，程序死机，程序死机又没有让系统死机，该程序占用CPU是0，点击代码任意处设置断点后，VS代码编辑器鼠标后面无响应了，只能关闭程序界面的"X"后，vs代码编辑器又可以响应了，请高手帮我分析是啥原因
解决方案四：
太长，你检查一下是否是死循环
解决方案五：
3楼的，谢谢，没有死循环问题，如果是死循环的话，cpu就是不是0
解决方案六：
看看是否有死锁
解决方案七：
5楼，谢谢，您好！我使用了lock，应该是不会有问题的。问题是发送数据到串口后，串口响应了一会儿后，后面就没响应了，数据也没有回答。
解决方案八：
串口通信没有问题吗？数据是否有发出去或接收数据？
