Please add missing documentation of the ports tag. It might be interpreted as related to multiple network ports, FreeBSD ports or else.
Looks like these can be divided into tcpip-ports, bsd-ports, and maybe physical-ports, though that doesn't seem like a terribly useful tag to me (example question is What does COM Stand for in terms of Serial Ports).
Any objections or improvements? If not, I can go through and retag for the tcpip/bsd distinction, and remove the physical ports.
