6.2. Country Code Configuration
Different countries have different requirements for how modems must
function. Therefore, before you use the modem, you must configure it to match
the defaults of the country in which you are using it.
If you are comfortable using AT commands, you can configure your modem
using AT commands. You must enter these commands in your communication
program’s terminal window.
To configure the modem for a specific country, execute the following AT
commands:
1. Type AT%T19,0,nn (nn stands for country code). Press [Enter]. OK is
displayed.
2. Then save the changes by issuing the following command:
AT&F&W
3. To verify that the correct country has been configured, issue the following
command:
ATI9
4. The country code is then displayed in decimal format.
The following is an example of country, AT commands, and result codes.
