I have 2 programs, one is writing to parallel port, and another is monitoring this port and taking actions.
I don't need a physical port for nothing, but in new computers without physical parallel ports the result of "inportb" is always "0xFF", avoiding this port monitoring.
Anyone have a virtual parallel port to solve this?

Would you care to rephrase that sentence. it contains a double negative and doesn't make sense.

If you don't have a physical parallel port, what is the programmes writing to?

In Windows XP you cannot access the hardware directly. You have to go through a device driver. That is probably where you problem lies.
