24 About built-in modems
is difficult and generally for experienced modem users
only. With your operating system, you must type long
AT command strings and you may need to send a vari-
ety of commands for each transmission. Also, you are
not always sure if your commands have been received
and executed by the modem.
To communicate with a modem directly from your oper-
ating system, use the ECHO command. Direct these
commands to the port your modem is connected to. For
example:
C:\ > echo ATS0=0>COM1 and press Enter .
This is an AT command that:
•
Stores a 0 into S register 0 to turn Auto Answer off
(ATS0=0). S registers are storage areas inside the
modem. The S registers hold values that the com-
mand set uses to control modem operations. For
more information on S registers, see page 35.
•
The command is directed to the modem’s port
(>COM1).
Whether you use your operating system or a modem
communications software application, you can send a
wide variety of commands to your modem. For a
detailed listing of modem commands see page 31.

Operating your modem
You can operate your modem either through a modem
communications software application or from your com-
mand prompt.
Most people use a communications software application
to operate their modem. Examples of these software
applications include Windows Terminal and HyperAC-
CESS** Lite for OS/2 Warp. These applications allow
you to operate your modem without using the Hayes**
AT command set—the commands that modems under-
stand. With these software applications, you operate
your modem by choosing menu items from a screen on
your computer. If you use a communications software
application, see the user’s guide that came with the soft-
ware for detailed instructions on operating your
modem.
You can also send commands to your modem from the
command (C:>) prompt of your operating system. Oper-
ating your modem directly from your operating system
note:
Some IBM Aptiva PCs in the U.S. and Canada, and some
models in other countries, may have built-in modems
with more features than the modems listed here. If you
have one of these models, refer to the modem documen-
tation that came with your computer.
note:
Most modem communication software applications also
allow you to send specific AT commands to the modem.
