TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol on the Internet and any TCP/IP network. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.

UDP ports use the Datagram Protocol, a communications protocol for the Internet network, transport, and session layers. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming, where dropping some packets is preferable to waiting for delayed data.

When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.

It's also used as an internal communication port for a router of type ZE H369A, in my case the KPN Netherlands (ISP) livery one (standard issue) but I think it may be any modem/router of this type that uses this port.

On its port forwarding configuration page/DMZ it self-explains this as:

''Attempts to enable remote access (via for instance port mapping or DMZ) for TCP port 8085 are invalid actions. This is due to the fact that this port is reserved for internal service on the RG with a higher priority than when it is used for port mapping.''

So that explains this port 8085 on TCP is used by the router itself.

BT Broadband (UK) open this port on their "Home Hub" ADSL routers with Apache listening; ostensibly in order to offer "dialup" (inbound) Support to users.
There appears to be no method for the user to defeat this other than replacing the Home Hub with a 3rd Party router (which could bring its own problems!)
This is likely allied to TR-069 RDA . Access requires a login that is not any of the internal user/pass combos and may well be (hopefully!) restricted to a specific BT address range.
