Or implement a simple message handshake protocol of your own? Like send a crude checksum value back to the sender, for it to decide what to do next. I've on and off been playing with shovelling GPIB instrument traffic over the LAN via UDP, as much as an experiment in programming as anything else, and found that even on a quiet LAN, you still get some packet loss with UDP. But it's relatively trivial to add a simple message handshake system, if you don't (or cant for whatever reason) use TCP. Take care with ARP etc, it's too easy to totally compromise a LAN with that. In some installations too, the IT peeps might be keeping an eye on ARP traffic, and "send the heavies round" if something odd is seen to be happening at your location, as it's a common LAN attack method. Google "ARP Games". It can be fun to fiddle on your own system, but....... Regards.
