modem tone. To turn Auto Answer off, use the com-

in the box your computer came in or the fax software
online Help for additional information.
Using the telephone with your
modem
While you are using the modem, do not pick up any tele-
phone receiver on that line. If you do, communications
will be interrupted.
Disabling Call Waiting
If you use Call Waiting, you may want to disable it while
using your modem. With Call Waiting, communications
can be interrupted when a second call is waiting to be
answered.
To disable Call Waiting, contact your telephone com-
pany. Different telephone companies have different pro-
cedures for disabling this feature. Also, some telephone
companies cannot disable Call Waiting. Your telephone
company business office should be able to tell you the
procedures and dialing sequence required to disable
Call Waiting.
note:
If you are using Auto Answer with a fax software applica-
tion, setting a high number of rings will allow you to
answer the telephone before the fax modem does.
A dialing sequence is similar to a command you type on
your computer. For example, in some areas the follow-
ing dialing sequence disables Call Waiting:
(# or *)70,,,(complete telephone number)
The dialing sequence you type on your computer might
look like this: *70,,,5554343. The commas (,,,) pause
the modem until the command is carried out, then the
telephone number is dialed automatically.
Call waiting will be disabled only
for the duration of
your modem’s current call and only from the calling end.
For incoming calls, you may find it helpful to change the
value of register S10 to a higher number. For more infor-
mation on S registers, see page 38.
Your modem communications software determines how
your modem operates with Call Waiting. For specific
instructions, see the user’s guide or online Help that
came with the communications software.
If your computer came with fax software already
installed, the fax software documentation was included
in the box your computer came in.
