CHAPTER 2: Introduction
Other uses include direct links to colleagues with modems, to banks, and to service
bureaus. You can also telecommute with your fax modem—work at home while
communicating with the office by modem or fax.
And of course, you can use your modem to exchange faxes with any fax machine in
the world, enabling you to communicate quickly with businesses and organizations
that do not have direct modem communications.
