I have no clue how many bytes I should read.

Every 12 msec data is coming to serial port, but ReadFile() function reads only 8 bytes at one instance. Why is it so?

while(stop != 1) {
  Grid.Execute(); //-> does the DoModal() and quits this function via the OnOK()
  switch(Grid.PressedKey) {
    case KEY_ESC: stop = 1; break;
    case KEY_ENTER: /*traitement*/ stop = 1; break;
  };
}

Thanks anyway for your answer

But i need to step out the DoModal() (return to the function which calls the DoModal())

Yes, normally it's the correct way to do this

But i need to step out the DoModal() (return to the function which calls the DoModal())
I created a Wrapper-Control which is called as the same way in windows-logic as in DOS-Console-logic

and in dos i have the following:

while(stop != 1) {
  Grid.Execute(); //-> does the DoModal() and quits this function via the OnOK()
  switch(Grid.PressedKey) {
    case KEY_ESC: stop = 1; break;
    case KEY_ENTER: /*traitement*/ stop = 1; break;
  };
}



I need to do this, because i reconstruct a DOS-Console Project into MFC
And both source-codes still exists (the DOS-Application should still exist after the MFC Application is ready)
So i need a source-code which can be traited in each logics
Because to adapt some 100000 lines of code isn't so cool

This "amphibian" source-code works, but i try to get it more beautiful
