Has anyone tried accessing serial ports from perl?

I tried installing Device::Serial and it crashes hard  (text is 
printed on the screen as if it was a console indicating it is waiting 
for the remote debugger to attach).

System Mac OS X 10.1.5
Power Mac G4 733 MHz

perl -MCPAN -e shell
try to install Device::Serial
it downloads it and then complains about not finding a serial port
quit
Plug in a Belkin USB F5U103-Mac serial port which becomes /dev/cu.modem
cd ~/.cpan/build/Device-SerialPort-0.12
perl Makefile.PL /dev/cu.modem
make test

Somewhere around test 85 the Mac crashes badly.  Even from user mode.

I don't know if this crash would affect different serial ports or 
non-SUB serial ports or whatever.

Any thoughts?

Thanks,
    Peter.
