hCom[comport - 1] = CreateFile(coms[comport-1],
        GENERIC_READ | GENERIC_WRITE,
        0,                                              // can't be shared
        NULL,                                           // no security attrs
        OPEN_EXISTING,                                  // comm devices must use OPEN_EXISTING
        0,
        NULL                                            // hTemplate must be NULL for comm devices
        );
