Not sure if this is distribution specific, but at least here, opening a
existent but unused COM port fails, even without this patch. Hacky test:

--- snip ---
#include <windows.h>
#include <stdio.h>
int main()
{
    FILE *fp = fopen("COM1", "w+");
    printf("%s\n", fp ? "successfully opened" : "failed to open");
}
--- snip ---

Could you provide more details under which circumstances the issue occurs?
