Troubleshooting Diagnostic Commands
If a data connection could not be established, you might be able to
determine the cause through the AT command interface.
Follow the steps listed below:
• Close all data applications.
Otherwise, these applications might start a retry command that will
interrupt your troubleshooting efforts.
• Unplug and re-connect the data cable.
This terminates any ongoing data connections.
• Establish basic computer-to-modem communication.
For instructions, see "Establishing Communication" on page 72.
• Query the last "Extended Error Code".
Although you might not be able to see the text as you type it, you should
see a result code returned to you.
