• When you use your software and modem, you will
rarely, if ever, need to send AT commands directly to
the modem. If you do want to enter AT commands,
however, you must do so from the software's terminal
mode.
To use AT commands in terminal mode
1
Start your data communications program.
2
Change to terminal mode (also called command,
local, direct, or dumb mode).
3
Type the AT command you need and press the
Enter key.
When you finish, you can return to the data communica-
tions program's standard user interface. See the soft-
ware's documentation if you need help.
The modem is in data mode when it is communicating
online with another modem, such as a modem at your
workplace or home. While in data mode, the modem will
not respond to AT commands. To communicate with your
modem without disconnecting the call, use active options
in the software's user interface or the +++ escape se-
quence. Communicating directly with your modem during
a call is seldom necessary.

Tip: Many programs for IBM PC-compatible computers
require that the modem initialize (or start up) with
command settings &C1 and &D2, the factory de-
fault settings, in the initialization string.
