Yes that is what I am suggesting :)

No I don't have examples.  I don't have a modem or any way to test or maintain modem code, so that is why I don't have any documentation or native modem answering in Mystic anymore.

The login.config file itself I believe tells you how to set what is executed upon connection so I would look there.  You could add -ST3 into Mystic so it shows MODEM as the connection type.  You could use -IP or -HOST options on the command line to pass in caller ID information that will show up using the IP and HOST MCI codes and this will be tracked in the user records as well.

You can do a similar thing to handle AX.25 packet radio to Mystic

... You can learn many things from children... like how much patience you have
