Hi,

Does anybody know if it is safe to connect the pin 10 (ACK) directly to the
GND (pin 18-25) without the need of an extra resistor in between? Is there a
possibility of damaging the parallel port of my PC?

I would like an external optocoupler to trigger an ACK on my PC with ACK set
to trigger the IRQ of the parallel port by pulling the ACK to GND.

Many thanks for your help,

Werner
