Hi All,

I am trying to write a driver for PCI based IEEE 1284 parallel port (Netmos 9805 chip)

When I enable the interrupts for my card, I am not able to mask them inside my ISR,
resulting in multiple interrupts getting generated. I write 0x74 in ECR to mask the
interrupts, but that does not seem to be working.

Anybody has any ideas about whats wrong here? Or am I not setting or resetting the right

Thanks in advance for help,
