D Installing Under Linux

Note: The preceding example places the modem on COM3. Your IRQ and port may vary. Substitute the IRQ and port values in the example with the values for your computer as listed in the results of the command issued in step 3. To set Linux to configure the modem at boot-up, use an editor such as “jed” and add the setserial command to the end of the rc.local file.

5.Once you’ve completed your installation, you must configure your modem for country- specific operation. See Chapter 2 for information on using AT commands to configure your modem for use in your country.
