Appendix D: Using AT Commands with the
Speakerphone Feature
If you are familiar with the use of AT commands to control your
faxmodem, you can develop customized ways of using the
faxmodem’s features that your communications software may not
directly support.
We do not recommend that you use AT commands unless you
are familiar with them. It is possible to disable your faxmodem
inadvertently.
To use the speakerphone feature with AT commands, you must
first go to terminal mode. Once you are in terminal mode, you can
use the speakerphone feature by following the procedures
explained in this appendix.
