问题描述
你能帮我吗?我需要使用笔记本电脑与通过串行端口构建的嵌入式板进行通信.
当我使用PC与主板通信时，用C ++编写的程序效果很好.但是，当我将笔记本电脑与USB串行适配器一起使用时，程序出错，显示"FlameMonitoring.exe触发了断点".我发现问题发生在m_ctrlComm.get_Input().我的初始化代码如下.
Hi,
Could you please help me out? I need to use my laptop to communicate with embedded board I built through serial port.
The program written in C++ works very well when I use PC to communicate with board. But when I use laptop with USB-serial adapter, the program goes wrong, showing "FlameMonitoring.exe has triggered a breakpoint". I found that the problem occurs at m_ctrlComm.get_Input(). My initialization code as follows.
m_ctrlComm.put__CommPort(COM_PORT);
m_ctrlComm.put_InBufferSize(1024);
m_ctrlComm.put_PortOpen(TRUE);
m_ctrlComm.put_Settings("115200,n,8,1");
m_ctrlComm.put_InputMode(1);
m_ctrlComm.put_RThreshold(6);
m_ctrlComm.put_InputLen(0);
m_ctrlComm.get_Input();
我错过了什么?此外，程序可以输入OnComm()，表示它接收数据.而且我认为它也能够将数据发送到嵌入式板.有什么建议吗?非常感谢您的帮助.

Did I miss something? Besides, the program can enter OnComm(), which means it receives data. And I think it is also able to send data to embedded board. Any suggestion? Many thanks for your help.
