Case G: Fax line shared with PC modem (no voice calls
If you have a fax line on which you receive no voice calls, and you also have a PC
modem connected on this line, connect your HP all-in-one as described in this section.
Since your PC modem shares the phone line with your HP all-in-one, you will not be
able to use both your PC modem and your HP all-in-one simultaneously. For example,
you cannot use your HP all-in-one for faxing if you are using your PC modem to send an
e-mail or access the Internet.
