56 kbps Modem: Checking and Changing Country Codes

The internal modem uses country specific parameters based on the setting of the country code. This code can be set with AT commands or by using the Modem Country Selector. (This application ships with computers outside the United States.)

Checking the Country Code

The easiest method for checking and changing country codes is to use the Mac OS 9 only application; Modem Country Selector. If you are using Mac OS X, and want to useModem Country Selector you must restart in Mac OS 9, as it does not function as a classic application in Mac OS X. Steps for using the Modem Country Selector application are listed in the Using the Modem Country Selector section.

As an alternative to Modem Country Selector, you can use AT Commands with the modem. The steps for using AT commands are listed in the Using AT Command sections.

Using the Modem Country Selector

1. Double-click the Modem Country Selector application icon.
The Modem Country Selector application opens.
Note: The country the modem is set for automatically appears in the pop-up country menu.

2. Choose the country in which the modem will be used from the pop-up menu.







3. Click OK.

4. When a message appears saying the modem is configured, click OK to quit the application.

The modem is now properly set up for use in the chosen location.

Using AT Commands in Mac OS 9

1. Open the Modem control panel.
Choose Null Modem 9600 from the Modem menu.




2. Close the Modem control panel.
A save dialog appears.

3. Save the changes to the Modem control panel.

4. Open Remote Access control panel.

5. Click Options.

6. Click the Protocol tab.

7. Select Connect to a command-line host:

This enables the Connect button.

10. Click Connect.
A modem terminal window appears.

11. type ATI5 into the terminal, then press return.
The country code is returned.

Important This document covers different modems. An additional code is needed to determine how to interpret the country code.


12. Type ATI12 into the terminal, then press return.
A register code is returned.

If S1, D1 or J1 is returned after entering ATI12, then use the S1, D1 or J1 column in the country code table. Otherwise use the first code column to determine what country code the modem is currently set to.

Once finished, you should choose your original Modem menu setting again.

Using AT Commands in Mac OS X

The process for checking the country code under Mac OS X is similar to Mac OS 9.

A modem terminal window opens.

10. type ATI5 into the terminal, then press return.
The country code is returned.

Changing Country Codes

The easiest way to change country codes in the modem is to use the Modem Country Selector in Mac OS 9. However you can also use an AT command to change the country code.

1. Use the procedures listed in the Checking Country Codes to open a modem terminal window.

2. Find the proper country code in the Country Code table.

3. If ATI12 results in D1 or J1, then type AT+GCI=xx, where xx is the country code you want to set the modem to.

Otherwise:

Type AT*NCx, where x is the country code you want to set the modem to.

Examples for D1 and J1 result codes:

To set the modem for proper use in Germany, use AT+GCI=42

To set the modem for proper use in Sweden, use AT+GCI=A5

Examples for non-D1 result codes:

To set the modem for proper use in Germany, use AT*NC6 OR AT*NC14 depending on which modem is installed in your computer.

To set the modem for proper use in Sweden, use AT*NC14 (the same setting is used in all non-USB internal Apple modems).

Country Codes
Use the appropriate Code column that corresponds to the result you received when you used the ATi12 command.
