When you select a modem from the list, the AT initialization string is set
automatically, as well as the speaker volume, speaker control, and number of rings
to answer. (You can modify these default settings.) If your modem is not on the
list, you can configure a custom modem and AT initialization command. The AT
initialization command is required for custom modems. Appendix E lists the AT
initialization commands for the ARN. Because your modem may use a different
set of commands, consult the manual for your modem.
Entering an invalid command can disable the modem. If the modem does not
initialize, you may need to change the asynchronous baud rate.
To access the window where you choose a modem, you must set the WAN Serial
Interface Type parameter to Async and the Line Media Type set to Hayes.
