Default Programming a UDP tunnel from scratch

I have a piece of equipment that runs on embedded, custom-programmable firmware. I can send and receive UDP packets with no problem from said system (I have established UDP connections with a PC host for a different application).

I also have about a half-dozen pieces of medical equipment that communicate via RS232 in different locations within my lab, which I want the above embedded system to talk to via a UDP/Serial tunnel, ideally with fail-safes built-in such that a default "shut down" command will be sent across the respective RS232 buses if a keep-alive signal is not received.

I've used the UDS/EDS product line with CPR in previous projects, and I'm betting I can use them in my application here, but I'm not finding instruction on how to format UDP packets or set up my fail-safes. I cannot use the Linux SDK, nor can I use CPR since my server is running on embedded (i.e., not any of the Big OSes) firmware. Can anyone point me in the right direction?
