Yeah, that was my thoughts!

Yes and no. You're right, I didn't have a driver, the Belkin serial
ports aren't supported under Mac OS X, so there was in fact no serial
port available at all.
This still begs the question how can a user process running the Perl
Device::Serial test scripts completely crash the Mac. But at the end
of the day, it isn't going to work anyway because I don't have any
serial ports (I was confused because I can actually access the serial
ports as USB devices under Virtual PC from Windows!).
On another Mac with a built in serial port I am just reading/writing
from /dev/cu.modem and it is working fine.
