That is because you are not opening them correctly.  If you read the
documentation for CreateFile() at MSDN, you will see the following:

    "To specify a COM port number greater than 9, use the following
syntax: "\\\\.\\COM10". This syntax works for all port numbers and
hardware that allows COM port numbers to be specified."
