I have my modem and my UPS both connected to serial ports with the same
interupt. Seems to work OK. These are both on the same card which was
modified (not a lot of fun) to share the interupt. JDR Microdevices

I'm not necessarily short on interrupts yet, but I figured it would be
interesting of the slower items could just
The parallel port kernel driver doesn't use the interrupt by default, it uses
polling. (It even says so in the boot messages, at least with my kernel.)

So I have taken every port to it's own interupt. But my question is: Why
