I think there has been other threads here regardng the hit-or-miss
nature of these USB-to-serial adapters.  I know when I needed one
to sync a Palm, I couldn't find one that did it right.  I think
I hit my head against three $30 adapters to no avail, but this
was four-five years ago.  

I'm not smart enough to talk about reactance, but I can tell you they're 
not quite the same.  It would stand to reason that a 30-year-old modem 
might've been developed to talk to its contemporaries.
