You first should make sure that the permissions are correct. What does the following command produce?.
$ ls -l /dev/cuad0
I'm trying to open communications on my computer's only serial port, but, whenever I do, I get the error "Device Busy: '/dev/cuad0'"
Please explain or specify what you are doing exactly.
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
