    Unrelated to this, I've noticed that port scanning a Palm IIIe connected to
    my network results in the Palm hanging and shutting down.  Some people use
    the Palm as a web browsing platform while their workstation does other
    things; my Palm recently got portscanned while I was doing that, which
    prompted me to see if the behavior was repeatable (it was).  Ping flooding
    the Palm makes it act funny, too.
