The ASR has activated in my car several times and it has never pumped the brakes, only forced my foot out of the gas (closed the throttle plates as SJW stated) and flashed the "ASR Active" light in the DIC.
The ASR system is pretty reliable, I don't recall ever hearing or reading anything about them having problems.
You don't need to hold the ASR button, it's a toggle, just press it. And there is no competition setting, it's either on or off.

Beyond the engine, the 1992 Corvettes benefited from a new standard traction-control system called Acceleration Slip Regulation which was developed in conjunction with Germany’s Bosch company. It used the ABS sensors to detect rear-wheel slip and apply the brakes to the affected wheels and/or throttle back power to maintain traction. In some instances, it would even cause the brake pedal to push back against the driver’s foot, thereby letting them know that the system was engaged. During wet and slippery conditions, the ASR was a significant safety feature which allowed the Corvette to be driven notably faster (in less than ideal driving conditions) although it would also result in a significant increase in rear brake pad wear (due specifically to increased braking control). Whenever a driver wanted to take their Corvette to the track, a dashboard switch could be activated to disable the system.
Found that all here.

I have a '95 LT1 auto and my ASR lights on the DIC never light up either. So either on or off. I understand that its always on and is basically on-demand when needed. I've tried to shut it off/on and don't notice a difference. Not sure if the switch is bad, bulb in DIC is missing, or something else. Anything else I'm missing to check to see if this system is operational and working?

If the indicator on the dash does nothing, probably the easiest way to see if ASR is functional is to induce some rear wheel spin in a safe place such as a wet or sandy parking lot. ASR will let you know if it's working by kicking back on the throttle (which you'll feel in the pedal), and pulsing the rear brakes (which you won't feel, but you'll probably be able to hear the ABS unit pulsing). If you can spin the rear wheels, ASR isn't operational.
