I am using SerialCom
In my main dialog's .h file I have the following.

// AdelphiX2Dlg.h : header file
//

#if
!defined(AFX_ADELPHIX2DLG_H__73D04BC6_4B69_4C03_A79E_C777887BC00C__INCLUDED_)

I setup the port in the main dialog .cpp file

  CString Comport = "com1";
  if(!(port.OpenPort(Comport))){
    MessageBox("Cannot open Communication Port.\nPlease Check Options For
Proper Setting","Error",MB_OK+MB_ICONERROR);
    return true;
  }
  if(!(port.ConfigurePort(19200,8,0,NOPARITY,ONESTOPBIT))){
    MessageBox("Cannot Configure Communication
Port","Error",MB_OK+MB_ICONERROR);
    port.ClosePort();
  }
  else{
    if(!(port.SetCommunicationTimeouts(0,260,0,0,0))){
      MessageBox("Cannot Configure Communication
Timeouts","Error",MB_OK+MB_ICONERROR);
      port.ClosePort();
    }
  }

=================================================================================================

Now I wish to use port within Web1a.cpp and Web2a.cpp

//using something like
port.WriteByte(sbyte);
//to send data out the serial port

What type is port?

As an example, if its type is CSerialPort then add a function to the Web1a dialog class like this:

// .h
CSerialPort* m_pport;

// .cpp
void CWeb1a::SetPort(CSerialPort* pport)
{ m_pport = pport;
}

The dialog will then be able to do

m_pport->WriteByte(sbyte);
