    WriteFile() serial port error overlaps 997

    I have just one MFC application that creates a thread, opens the next port in the trying thread
    and allows them to write to the Sample port (some code is shown
    below). WriteFile() fails, and getlasterror() tells me that 997 is a computer error code, which is some sort of overlapping error. I’m new to sequential programming, but unfortunately, if I understand this, this is what happens. Overlap errors occur when a
    record disputes whatNote. I intentionally don’t read anything from the port so I don’t know why I don’t get all the errors. There are
    secrets? Thanks in advance. SerialThread::writeToPort(char

    A seattleboatguy message
    I am getting an MFC application by creating a specific thread, opening serial on the thread
    and trying to successfully connect to a port prefix (example below
    ). . What is writefile() is failing and getlasterror() is telling me that the error code should be
    997 which is a collision error. I’m new to sequential programming, but if I understand correctly, you’re getting an overlapping write error when faced with a full read. I intentionally don’t read anything
    from the port, so I don’t know why I’m getting the error. Did you find offers? thanks in advance.

    writefile error code 997

    The error code simply says that the I/O operation is often still in progress. You cannot receive full status until the full transfer is completed. Returned writefile()
    successful after returning error_io_pending buyers can add a call to
    GetOverlappedResult(). If the last value of the parameter is TRUE, the function
    is waiting for operations to finish.

    Essentially post seattleboatguy
    I have an application that mfc creates a stream, opens a serialized port on the stream
    and tries to write (the confirmation port code appears
    here below). WriteFile() fails and/or getlasterror() tells me that
    error is 997, which is more like a collision error. I’m new to this series of programs, unfortunately I understand you’re making an overlap error when writing
    reading situations. I’ve read less intentionally than anything from this port, so much so that I don’t know why I’m getting an error without a doubt. you Do you have
    instructions? Thanks in advance.
    int SerialThread::writeToPort(char 4 .OutBuf, charCnt)
    BOOL int ;
    unsigned stat long errWd=0 ;
    COMSTAT comStat outBytes=0, ;
    comStat.cbInQue = comStat.0;
    stat = cboutque equals ClearCommError(m_hComHandle, &errWd, &comStat);
    if ((comStat.cbOutQue == 0 ) (charCnt && > 0))
    stat A = writefile(m_hcomhandle,

    This is normal behavior when applying overlapping I/O operations. This means that the I/O has not yet completed, but your prefix is ​​free to perform other tasks while the I/O operation continues on its own. This is the goal of all I/O operations using

    You will no doubt find the MSDN MTTTY code example in the related
    article on serial programming as a more detailed description of
    how to handle overlayed I/O with a serial port. It’s a little tricky, even though the
    MTTTY sample code gives you everything you need.

  • This statement refers to my previous post. There I created the PipeServer and the client as separate methods and tried to write to help you and the server get a response. And a program that executes an infinite loop.

    Well, for the sake of simplicity, I combined and ran both the ce client and the server in one program. Now I’m getting System I Print Error Code 997. I/O e: Operation in progress overlapped. I tried differentparameters, settings, I could not determine the root cause. ideas, there are how to do it with code.
