Hi
This makes me feel really stupid. It was working all along. The cable that i was using attached to the parallel port was switching all the pins around and doing strange things. I thought of it...

Hi
yes the HIGH of the parallel port should be between 4.7 and 5v, and an LED operates at around 2-3 volts depending on the type and age. So i have a resistor attached in series to decrese the...

i could try booting dos, would take a while finding a floppy and all that.. but i can give it a go.

yes it is connected to the motherboard.
With the Led's I am using the propper grounds, 18-25 (one of them). I checked in the bios and its on normal mode, so I have no idea at this stage.

its been baffling me as well. Because i want to be able to connect this board that i have written the main code for. For home automation and random projects.
But it seems otherwise to not work. I...

I am mesuring pins 1-9, although the data pins that i require are 2-9. The leds are grounded to one of the many grounds.
Does it have anything to do with the mode that the parallel port operates in?...

Hi,
I have attached my code. To run the code I am compiling it, gcc parallel.c -o parallel, chown root parallel, and chmod u+s parallel which allows ioperm() to return a positive value not -1.
To...

Hi
I am trying to get a program in C to write data to the parallel port byte wise.
I have got the program running of sorts, I can write to the port and then read the data back with the same value...
