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.
