ttl test program not working (case 10436)

[ARLUser]

I have constructed the circuit. Positive of the led to pin 2, negative of the led to the resistor 250 to 470 ohm range, resistor to pin 19 on the connector.
When I plug in the connector to lpt1, the led is already lit. All data pins are 3.3v changing the bios for epp or ecp makes no difference. Once the machine boots all data lines are high. Verified this on a second computer.

I just attached my test device to the computer that will be used for data collection. The led is lit as soon as the device is plugged into the parallel port.
I run the ttl i/o test and enter 888 as the port, set byte value to 0 and send byte now. It turns the led off. So monitor port 888 = 0. I enter 1 for the byte value and 500ms for duration, send byte now, and the led turns on then off. a value of 255 for byte also works. now the question is hoe to program the lpt port to turn on at the same time a stimulus tone is being output.
