following AT commands in the G30 terminal window:
• ati7—prompts G30 identification

3. Make a CSD call from the G30 to the line modem or the reverse using the
atd and ata
commands in the appropriate window
4. Verify that a connection between the two modems is established
5. Select any file to transfer between the two modems
The file can be any existing file, or a new file created specifically for the test.
6. Send the file either from the G30, or to the G30, through the terminal application using the
terminal application’s send/receive file options
