2000 models do not have the serial interface - came in 2004. My guess is that the 2000 is more or less the same as my '91, which only had two variables for turning them off - timer and speed, whichever came first.
On mine this did not fit my riding style, so I removed the non-power/non-blinker cables. Now it turns on at the push of the switch, and stays on until I push again. My '88 XL did not have a module, and you had to hold the switch in for the blinkers to do the same - totally idiotic (the japs had at the time a three-way sliding lever with push-off: simple, and working).
Anyway, check you wiring diagram, and you will find that it is really simple (except multiplexing which has been around for some years on European cars; they are a nightmare ot try to understand. if sometihing fails, you're in trouble).
