AT Command

Description

 

 

 

AT

The command prefix that must be typed as the first two letters of

 

all AT commands except +++ and A/. This prefix gets the

 

AT tention of the data module.

 

Note: The characters of the AT prefix must both be typed in

 

either uppercase or lowercase letters (AT or at will

 

work, but At or aT will not). Typing a space between

 

the AT prefix and the next command on the line is

 

optional, but do not separate the two letters “AT” with

 

a space.

D

The Dial command. This command follows the AT and precedes

 

the number that you wish your data module to dial. For example:

 

atd71204 [ Enter ]

 

Note: Other commands may precede the D command, but

 

any characters following it will be interpreted as part

 

of the number that is to be dialed.

A/

The redo or Again command. This is one of the two commands

 

that does not require the AT prefix. To repeat the previous

 

command line exactly, type A/ without pressing [ Enter ].
