Here's what to do:
1. Make sure the telephone cord is securely connected. Your Read me first book
shows how the cord should be connected.
2. Make sure the telephone line works by plugging a working telephone into the
same telephone outlet that the computer was plugged into. Then make sure
you can place a call.
3. Make sure you are calling the correct number, and that you are using the
correct communications settings. For additional help, see the user's guide for
your communications software.
4. Make sure no one is using the telephone while you are communicating with
another computer.
5. If some communications programs work but others do not, there may be a
configuration problem. For additional help, see the user's guide for your
communications software.
6. Make sure your modem cord is connected to an analog telephone line. For
additional help, see "Setting up communications" on page 18.
7. Make sure the modem adapter card is installed correctly. For instructions on
installing adapter cards in a desktop system unit, see "Adding and removing
adapter cards" on page 81. For instructions on installing adapter cards in a
minitower system unit, see "Adding and removing adapter cards" on
page 103.
