I got a LED and touched it to the positive and negative ends of two 1.5v AA batteries in a serial configuration. The LED lit up. I then crimped on pins to the end of the LED wires and again tested it with the batteries. Again, I saw the light. I plugged said tinned pins into the 2nd and 25th pinout of a 25 pin port (the parallel port): positive lead to the 2 pin, and negative pin to\ the the 25 pin. I then executed the following program: I have written a small program: #include <stdio.h> #include <dev/ppbus/ppi.h> #include <dev/ppbus/ppbconf.h> int main() { int fd; while(1) { ioctl(fd, PPISDATA, 255); } } I am expecting to see that LED light up, flashing if not creating a solid light. However, I am not. any help would be very much appreciated Sincerely, David To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
