sending binary data from serial port by visual c++

[ilhanuludag]

hello everyone, I am a new member. For my project I have to send binary data (like 10001110) to the db9 rs232 port. I use visual c++ 6.0. I found some codes but they could not work properly. Can anyone give me a c++ code for this problem? Thank you...

what is the problem? do you have functions to read/write the serial ports? are they not working correctly? don't you get anything tranbsmitted when you send data?
have a look at

    CSerial serial;
 
    // Attempt to open the serial port (COM1)
    serial.Open(_T("COM1"));
 
    // Setup the serial port (9600,N81) using hardware handshaking
    serial.Setup(CSerial::EBaud9600,CSerial::EData8,CSerial::EParNone,CSerial::EStop1);
    serial.SetupHandshaking(CSerial::EHandshakeHardware);
 
    // The serial port is now ready and we can send/receive data. If
    // the following call blocks, then the other side doesn't support
    // hardware handshaking.
    serial.Write("Hello world");
 
    // Close the port again
    serial.Close();
    return 0;
}

I have used this code and it says "Just call the Write method and supply a string. The Write routine will detect how long the string is and send these bytes across the cable."
But program give some errors while building the exe file.

the HelloWorld.cpp program from
http://www.codeproject.com/system/serial.asp
compiles and links OK for me - when you linked did you include the serial.cpp file?

to run it I switched off hardware handshaking then it transmitted "hello world" to a another PC via the serial port at 9600 baud
