parallel port (Write and read at the same time)

[Marco >.<]

Dear all,
I read a webpage, it said pin #1 can be in / out. pin 2 to 9 is out only. Now I have a circuit which will create interrupt. I need to use at least one pin to be in port and check when the interrupt happen
My first question is
How can I set the pin #1 to be inport? Can some other pin be in port too? If Yes, How can I set other pin? Use Visa again??
My Second question is
I need to generate a clock pulse which is for the same circuit. Can I put the Visa read and write in the same while loop?
thanks

-Marco

I'm not an expert on the parallel port, but you might also want to look at the parallel port examples that use the "Port I/O" functions. (I'm assuming you have LV 7.0 or later.) These program the parallel port at a lower level, and might give you more control.

I hope this helps.
