Manual selection of incoming data/fax calls
Certain service providers require that you preset your
phone to receive the incoming data or fax call, rather
than having the phone automatically detect the call type.
Note: Check with your service provider to see if “pre-
arrangement” of data and/or fax calls is necessary.
Most popular data and fax programs allow you to send
additional initialization commands to the modem when
the program is launched, or when the modem is instructed
to receive a call. You will need to modify your phone’s
modem configuration in the data or fax software so that
it sends the following special initialization string to the
modem:
96
To preset your phone to receive a data call:
AT+CSP=1
To preset your phone to receive a fax call:
AT+CSP=2
You should only have to make this modification once;
these settings typically are saved as a part of your data or
fax program’s settings. Please refer to the documentation
or online help files for your data or fax application when
modifying your modem’s initialization string.
When the software has sent the proper command to your
phone, the phone will display Ready for data reception
or Ready for fax reception momentarily, along with
either a d or f status indicator at the start screen.
Once your phone is preset for either data or fax reception,
you cannot receive incoming voice calls. You must either
remove the data cable or turn the phone’s power off and
back on to restore normal voice call reception.
