Specify Modem Initialization Strings. Initialization strings are commands that are sent directly to the
modem to specify various aspects of its behavior. Type any modem initialization strings directly in the
box to the right of the appropriate speaker control for each modem. Remember to leave the letters AT at
the start of your initialization string. (PhoneSweep’s default initialization string for each modem is:
ATE1Q0V1).
Important: Do not use the command &W in your initialization strings. This will write to the flash ROM
of the modem. Since PhoneSweep sends the initialization string before every call, this will burn out the
flash ROM after a few thousand calls.
Initialization strings are not well standardized. Therefore, we recommend that you check the
documentation for your particular modem for more specific information. The following table contains
some of the more common initialization settings.
Initialization
String
Description
ATS6=x
“x” denotes the number of seconds your modem will wait for a dial tone. Increasing
this can be helpful where PhoneSweep disables a modem because it does not get dial
tone in time.
ATS7=x
“x” denotes the number of seconds your modem will wait for carrier. The common
(U.S.) default is 60 seconds, though European modems are set to 50 seconds. This
must be at least as large as the Timeout in Seconds value set on the Time sub-tab.
ATS8=x
“x” denotes the number of seconds that the comma character causes the modem to
pause. The common default is 2 seconds. Increase this value only if you want to
reduce the number of comma characters required to specify a pause interval.
ATS11=x
“x” is the length in milliseconds of each Touch Tone. If you are scanning an older
phone system, you may need to increase the value to ensure that your phone system
will recognize each digit dialed.
If you need to use multiple commands, they should be in the format ATS6=xS7=x.
After you have set up your modems, click the Save button.
PhoneSweep will prompt you if you try to quit the program or start a sweep without saving your changes.
These settings can be changed at any time during a sweep, but they will not take effect until the next call
the modem makes.
The modem baud rate is set on the Dialing sub-tab, under the options Setup tab.
