I'm looking for a 5 volt signal.
I have wires plugged into pins 2 and 25 of the parallel port.
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);
}
}
and have it executing...
I have a multi-meter with the positive lead touching the pin 2 wire and the negative lead touching pin 25 wire, but i am not registering any voltage.
=(
I am sad.
I have recompiled my kernel to disable plip and enable ppi. The following is a snipet of my kernel configuration:
# Parallel port
device ppc0 at isa? irq 7
device ppbus # Parallel port bus (required)
device lpt # Printer
#
# 2002 oct 27 - removed plip and added ppi.
#
#device plip # TCP/IP over parallel
device ppi # Parallel port interface device
#device vpo # Requires scbus and da
any help would be very much appreciated
