So you have the db9 to rj-45 adapter wired up correctly with a terminating resistor and a 6 wire cable to the first black jaguar? And you have terminator on the other side as well?

I suspect the problem is in the "telephone wires" which are backwards from the wires the Jaguars use. If you hold a wire flat, the connectors should face different directions.

Also, do you have your initialization right? It appears that you have an extra comma at the end and the compiler doesn't like that.
