How To Use AT Commands
Usually, your fax and data comm software controls
the modem for you. However, you may also want to
use the AT commands. These commands give you
complete control over your modem. You need to be
careful when using these commands, because they
can cause your software to loose its ability to control
the modem. If you do find that an AT command has

the factory default settings. You can also type
AT&F&WZ to go back to the factory default setting.
