I am trying to use Linux Mint,
but I also need support for a landline modem.
any suggestions on how to get Linux
working with a modem?
Here is a list of Linux Compatible sound cards.
Genuine Sound Blaster (non-win modem) cards were original the fool proof method. Some other cards work too. Hardware cards, not software cards.
Some distributions of Linux work with some soft cards too.

External real modems can be your fiend.
