I was wanting to test out operating my printer using interrupt-driven I/O rather than polling. So I executed "tunelp /dev/lp1 -i 7". That seems to work -- for a while. If I do "tunelp /dev/lp1" it will report that the parallel port is using IRQ 7 for a while, and then will revert to reporting that it is using polling. This reversion happens even if I'm not using the printer at the time. (I do have lpd running, but nothing queued.) Does anyone have any idea what might be going on? (I am using kernel 2.0.23 and Slackware 3.0.)
Thanks,
