Using AT Commands
To make a data call using AT
commands from an asynchronous
terminal, follow these steps:
1. From your terminal, enter the AT
dial command (ATD) and the
number you wish to dial
(2345678) for example), ending
with a carriage return (shown
here as <CR>):
ATD2345678 <CR>
The letters AT stand for
Attention, D for Dial. (Either
ATD or atd will work.) A blinking
terminal symbol appears on the
phone's display next to the word
DATA.
When the call connects, the word
CONNECT or COM appears on
the terminal screen. The phone's
display returns to normal, except
that a steady terminal symbol
continues to be shown to the left
of DATA.
If the call cannot be completed
(the called terminal was busy or
did not answer) an error message
appears on your terminal screen.
2. To disconnect the call, use the
following procedure:
• Enter +++ from your terminal
OK appears on the terminal
screen.
• Enter ATH <CR> from the
terminal.
The call disconnects, and the
terminal symbol on the phone's
display disappears.
Note: When you use the AT
commands, the message ERROR
will appear on the terminal
screen if the command is
entered incorrectly. Please refer
to the Data User's Guide for
more information on using the
AT commands.
