Detecting Start of TeleOp Mode

I'm not sure if I'm overanalyzing the problem, but I don't think it's as easy as knowing when the TeleOp routine begins (and hybrid ends). During a game, hybrid mode begins and runs for 15 seconds. Then there's sometimes a pause between the end of hybrid and the beginning of teleop - last year the referees took this time to remove unplaced keepers from robots. During this pause I *think* the robots are in TeleOp mode but they aren't allowed to receive feedback from the driver stations - I just don't know and this is where I was hoping someone here knew. I would like to be able to have the robot code know the instant the radio communications come online and the robots are able to be controlled remotely.

Is this as simple as knowing when the teleop code begins, or is there something a little more crafty required?

Thanks!

Danny,

This is how the mode transitions during a round:

Disabled->Autonomous->Disabled->Teleop->Disabled.

If you look at the code (specificially ifi_frc.c/main()) I released for the 2008 game, I took a cut at simplifying the code. You'll want to look at the Teleop_Init() function, which does exactly as you describe. If you're not using my code, you could probably re-structure your code along the same lines.
