For my purposes, I ended up not needing to use Erlang at all. Pyserial and a
tiny Python script worked just fine. In the production context, someone else
will be managing the dialup to IP conversion, so all I needed was a little
script to test with so that I didn't have to edit, compile,
negotiate-with-ops-team, test.

Anyway, Richard, thanks for the Pyserial tip! Worked great.
