[rtl] lpt interrupt
Has anyone tried using the lpt port interrupt (irq7) for testing
rt-isr routines? I've done what I think are the proper incantations,
but no interrupts are generated.
request_RTirq( 7, irqHandler ); // install irq handler
outb( 0x1c, 0x37a ); // enable int generation on lpt1
But when I pull pin 10 low to generate an irq, the service routine
never gets called. I do check that the request_RTirq doesn't return
an error.
I've checked the contents of /proc/interrupts. It never contains
any record of irq 7's use when the rt module is installed. But I'm
not certain that it will show up for rt type modules.
Any ideas?
Regards,
Jim.
