read/write to paralell port?

[kmagas]

I have alot of experience with the serial port in LabWindows. But I cannot find any information about the paralell port. How do you access the port? Is it possible to read/write hi or lo to each pin?

There is some useful stuff here.

You will also need the PortIO routines in the Utility Library. (inp(), outp() etc) (And possibly the CVI low-level support drivers.)

Hi kmagas,

The link provided by jr_2005 is quite informative.  It is possible to write HI or LOW to some of the pins (not gnd, obviously 😉 ); however, if you read the pdf file, you will know how to set the BIOS and the address offset for the data line you wish to write to.
