(The answer was 'No, it doesn't.')
Here is a starting point for you. All it does is spin waiting to see
the bit change, and then stop. You need to fill in what it needs to
do after that.
To build it, grab <URL:ftp://people.redhat.com/twaugh/libieee1284/
alpha/libieee1284-0.0.0.tar.gz> and install it (./configure, then
make, then make install).
Then build the attached program like this:
gcc -O2 -W -Wall -c -o time.o time.c
libtool gcc -o timecomm time.o -lieee1284
If you are running a 2.4 kernel, adjust the permissions on the
appropriate /dev/parport device, and run timecomm as a normal user.
If you are running a kernel earlier than 2.4, upgrade. ;-)
[Alternatively, run it as root. But don't run things as root if you
can help it.]
Tim.
