Parallelput and parallel port problem

[ADS]

I am trying to test out the parallelput command on a miniature level before I write up my whole program. I want the program to light up 1 LED then after 10 seconds turn if off

The problem is that all 8 LED lights light up and none of them turn off after 10sec

I have tried a variety of codes such as "paralellput(2#00000001)" and "parallelput(1)"

Turing:

<parallelput(2#00000001) delay(10000) parallelput(2#00000000)>

I am using turing 4.1.1


How could this be fixed?
