Read parallel port

$

Hi Everyone,

 

I am trying to read data from the parallel port with VISA.

 

The basics: I'm using a PC running Windows 7, with LabVIEW 2010 (SP1). NI-MAX shows that I have NI-VISA 4.6. I have checked the parallel port in the BIOS and it is set to ECP, which seems (from previous posts) to be the correct setting .

 

MAX shows the parallel port with the VISA alias "LPT1", and says the device is working properly. However, when I use the VISA test panel in MAX to read from LPT1 it returns the error code BFFF0015.

 

A simple VI in LV 2010  that calls VISA Read with "LPT1" (or "ASRL10") as the resource name also fails, returning the error code BFFF0072.

 

I've done this in the past with the "In Port" and "Out Port" functions, but these are no longer available.

 

Thanks for your advice, and best regards,

 

Geoff
