Hello,

I am writing a program for a Win98 target that needs to use the parallel port as an interrupt driven bi-directional device.

What I know is how to initialize the port using CreateFile, how to use ReadFile to read a stream of data and how to close the port.

If I want to write an Interrupt service routine to do "handshaking" of each byte, how do I get Win32 to notify me that an interrupt has occured?

Question: Specifically, what triggers a Win32 notification that data has arrived at the parallel port?

Any help is appreciated.

Bob
