"gone" means that somebody unplugged a PCCARD modem, and it's very
important to check it before you start talking to thin air.
You could #ifdef it, but you'd gain only epsilon.
Instead, how about building the list of ports to scan outside the ISR?
You'd lose the null pointer check PLUS the check of "gone," so you'd save
more like a delta than an epsilon. And there'd be no need for an #ifdef there.
