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.
