If I try to open a com port "com10" or higher I get an run-time error. Com 
port "com1" - "com9" works fine.

(I use virtual comports from Tibbo, and when I use Microsoft�s HyperTerminal 
it actually works)

Here is my code to open the comport!
Works fine for "com1" to "com9".... What is wrong?
//---------------------------------------------------------

hComm = CreateFile("COM10",
                      GENERIC_READ | GENERIC_WRITE,
                      0,
                      0,
                      OPEN_EXISTING,
                      0,
                      0);

   // IF THE PORT CANNOT BE OPENED, BAIL OUT.
   if(hComm == INVALID_HANDLE_VALUE)
      Application->Terminate();

//---------------------------------------------------------
