setcommport

I use this command to initialize my Comm Port in port 1

m_Comm.SetCommPort(1);
m_Comm.SetSettings("9600, n, 8, 1");
m_Comm.SetPortOpen(TRUE);

How to initialize one more comm port which is in port 2?

How to control both comport? Example: I want to receive data from comm1 and send whatever i receive to comm2.

Thank you...........
 

setcommport(

its quite simple. You just instantiate another object from Communication object. I don´t know wich object, but, let´s suppose you did this:

COMMSerial Comm;

m_Comm.SetCommPort(1);
m_Comm.SetSettings("9600, n, 8, 1");
m_Comm.SetPortOpen(TRUE);

alright? now, just do this:

COMMSerial Comm_2;

m_Comm_2.SetCommPort(2);
m_Comm_2.SetSettings("9600, n, 8, 1");
m_Comm_2.SetPortOpen(TRUE); .

best regards, and happy holidays

just add another control, if only your PC has two serial ports.
 

posting comm port event

Yes my PC have two comm port.

am I need to add another "Microsoft Communication Control" (as shown in the picture) or not?

Showing in the picture is what I already did and I already add another comm port initialization as suggested above. when I compile the program, everything is o.k. But when I try to execute the program, nothing happen (the program doesn't executed). Anybody know what is wrong?

Thank you....

how to do port initialization in c

yes, you will need two control if you use mscomm control.

But why when I run the program, Nothings happen?
 

m_comm.setcommport(1);

did you initialized the code seperately? and check which port # when there is a COMM event?

for Serial port initialize I do this:

// TODO: Add extra initialization here
m_mscomm.SetCommPort (4);
m_mscomm.SetSettings ("9600,n,8,1");
m_mscomm.SetPortOpen (TRUE);

m_mscomm2.SetCommPort (5);
m_mscomm2.SetSettings ("9600,n,8,1");
m_mscomm2.SetPortOpen (TRUE);

return TRUE; // return TRUE unless you set the focus to a control
}


If there is Comm Event in Port4, I do this:

void CBasicmodemDlg::OnOnCommMscomm1()
{

UpdateData();
CString data;
CString str;
COleVariant myVar;

myVar = m_mscomm.GetInput ();
data = myVar.bstrVal ;

m_rx = m_rx + data;


UpdateData(FALSE);
}


And if there Comm Event in port5, I do this:

void CBasicmodemDlg::OnOnCommMscomm2()
{
// TODO: Add your control notification handler code here
if (m_mscomm2.GetCommEvent()==2)
{
VARIANT in_dat;
in_dat = m_mscomm2.GetInput();
CString strInput(in_dat.bstrVal);
m_tx = m_tx + strInput;
UpdateData(FALSE);
}

}
