Hi,
   you can use the Microsoft communications control for sending and receiving data from the serial port.
Your application has to be dialog based.
Go to : project->add to project-> components and controls
open the registered activex controls and select Microsoft communications control to insert it.
A new icon will appears in the controls menu. Add it to your application. Now from class wizard add a control to it(m_comm). To select and open the port write the following code:

m_comm.SetCommPort(1); // or any port
m_comm.SetSettings("4800,n,8,1");  // you can select the baud rate from here
m_comm.SetPortOpen(TRUE);

to send data write the following code:

m_comm.SetOutput(COleVariant(string)); // the output data is in this string

to receive data :
 COleVariant myvar;
myvar = m_comm.GetInput();
CString str(myvar.bstrval);

m_myedit+=str;  // put data in editbox
UpdateData(FASLE);

If you want the data  to appear every time the buffer is full , double click on the icon the you put in you dialog and select ok and place the above code in this method.
Or you can set a timer to get the data in buffer with the above code which i prefer more.

Regards,
Mazen
