Dick can't find fax software anymore. Leo says that nobody really faxes with software anymore because the fax hardware simply isn't there anymore. This can be problematic since real estate companies still use hard copy faxes. Going forward, using an online service like eFax is the way to go. FaxZero is another. An all-in-one printer with a fax option is also possible. But he'll have to have a phone line to do it.
Another source is to look at is AlternativeTo.net. He may be able to find a fax utility there.
