Parallel Port question

[Love a Sheep]

I am writing to the parallel port in LV7. I had done this ok in LV6
before and in windows XP. I had to load a special program first but
all is well. In LV7 I get the error message

stopped at 0x1D8 of sub vi in Port old 6.x.vi.

I am using the R/W to parallel port - I cannot find anything in
LabVIEW 7 - can you help?

Thanks

You can read and write the parallel port using VISA. A simple read and write may do it for you, although VISA has a lot of other functions, should you need them. Make sure you read the note about VISA and the parallel port in the docs. Find it by doing a search on parallel port in the LabVIEW help.
