Maybe this is because you pressed cancel button and
was set somewhere else? It returns FALSE when cancel button is pressed.
From CommConfig dialog description:
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call *GetLastError*.
I think drvCommConfigDialog should return the same. Maybe adding
and SetLastError(ERROR_SUCCESS) will solve the problem?
