Operating your modem     B-3
Using the Auto Answer feature 
If you use a modem communications software program, it 
may require your modem to be set for 
Auto Answer
. The 
Auto Answer feature lets your computer answer calls from 
another computer automatically.
Your modem communications software determines how the 
modem operates with Auto Answer. Some fax programs do 
not require you to type an AT command to turn Auto Answer 
on or off. For specific instructions, see the user’s guide that 
came with the communications software.
To start the Auto Answer feature from your communications 
software, use the command: 
ATS 0 = n
. This command tells 
the modem to answer a call after a certain number of rings. 
To set the number of rings, replace 
n
 with any number from 
1 to 255. 
If you do not have a voice modem, turn Auto Answer off 
when you are not using your modem. Otherwise, callers will 
be greeted with the modem tone. To turn Auto Answer off, 
use the command: 
ATS 0 = 0
.
In some communications software programs, you may need 
to select the “Auto Answer On” or “Auto Answer Off” option 
to turn off the auto answer feature.
If your computer came with fax software already installed, 
use the fax software documentation included in the box your 
computer came in or the fax software online Help for 
additional information.
Disabling Call Waiting
If you use the Call Waiting feature on your telephone, 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 company. 
Different telephone companies have different procedures 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.
A dialing sequence is similar to a command you type on your 
computer. For example, in some areas the following dialing 
sequence disables Call Waiting:
(# or *)70,,,(complete telephone number)
The dialing sequence you type on your computer may 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 information on S 
registers, see “S registers” on page B-14. 
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.
Note:
If you are using Auto Answer with a fax software 
program, setting a high number of rings will allow you to 
answer the telephone before the fax modem does.
