Hi

I used open function to open bluetooth port on MacOS 10.5.1.

My code is as below

int fd = -1;
fd = open(Bluetooth port path,O_RDWR + O_NOCTTY + O_NONBLOCK +
O_EXLOCK);
if(fd == -1)
printf("\nPort open failed..");
else
{
printf("\nPort successfully opened..);
close(fd);
}

but it hangs in open function, it is not returning....i also tried
with various flags..
Note :: Same thing works on MacOS 10.4(it's return success or failed)

What may be the problem ?
