[ntp:questions] Atom PPS with parallel port

I would like to use the Atom driver (22) on a Linux system with a
parallel port. It is not clear to me from the scattered info I have
found on internet if this is going to work.
Using a modern Linux kernel with the PPS module, is it possible to
symlink /dev/pps0 to a parallel port device and then connect the PPS
signal to the ACK input (pin 10)?
If not, what else is required to get this working?
Examples always refer to the use of a serial port DCD input, but for
best accuracy (in the microsecond range) I think the parallel port
(no RS232 drivers/receivers, no funny UART that may delay interrupts)
Any other suggestions for an accurate PPS input?
