[comp.sys.ibm.pc.hardware] Parallel Port

i'm am trying to set the data bits on my parallel port. So i wrote a program i
n basic that should set them all high ( lprint chr$(255)) I put the program in an infinite loop, But when I tested the data pins they always remained low.  I also tried grounding the acknowledge pin, but that made no difference.  I want to be able to be able to have a constant value outputting on the parrallel bus.
I am positive there is nothing wrong with my equipment.  I would appreciate any assistance given.
Very Respectfully,

I am trying to have parrallel port data pins keep outputting a constant value.
I have tried using lprint chr$(ascii value) but when i test the data pins they
are always low.  I have tried grounding the acknowledge pin bu that madeno difference.  I would appreciate any help given.
