CHAPTER 2: Quick Start
2.4 Basic Operation
To assist you in getting the modem
up and running, the following
sections provide basic information
for each of the modem’s primary
operating modes. For additional
operating information, refer to the
remaining chapters in this manual.
If you encounter difficulty, refer
to Section 2.4 at the end of this
chapter.

Two-wire dial Hayes emulation
mode is the factory default
configuration for the modem.
Hayes mode operation is explained
in detail in
Chapter 5 .
To dial a telephone number
in Hayes mode, type the Hayes
command AT D on your computer
or terminal keyboard followed by
the number you want to call. For
example:
AT D 5551212 [CR]
Dashes or spaces may be
included for clarity, but they are
not necessary. (The modem will
ignore them.) A carriage return
[CR] or period is required at
the end of each command line.
(On most keyboards, the carriage-
return [CR] key is labeled “Enter”
or “Return.”) In response to the
command line shown above,
the modem will dial the number
555-1212.
If you have to dial an access
code such as 9 to dial out of your
building, insert the access code
and a comma in the dial string.
AT D 9,5551212 [CR]
The comma causes the modem
to pause for 2 seconds. This allows
the modem to detect a second dial
tone (after the access code) before
dialing the number.
The default dialing mode is pulse
dialing. To change to tone dialing,
insert a T after AT D: AT DT. To
change from tone dialing to pulse
dialing, insert a P: AT DP. The
specified dialing mode will remain
active until the alternate mode is
specified or the modem is reset.
When a phone number is
successfully dialed, a “CONNECT”
message will appear on the
computer screen, and the LCD
on the modem will display a status
screen that typically look like this:
D TR MR RS CS TD
9600 CD RD
TD and RD will be flashing (to
