Hi ,
I am trying to access the parallel port and use it as a general purpose I/O , i used VISA , but it only access 8 bits (pin 2->9) and pins 11 , 12 must be grounded.
I want to use the pins from (1 to 17) as Inputs and outputs.

By design, a parallel port sends data out on pin2:9, and you cannot just use it generically.
