6. AT Command Summary

The AT standard is a line-oriented command language. AT is an

abbreviation of ATtention and it is always used to start sending a

command line from the terminal equipment (TE) to the terminal adaptor

(TA).

The command line consists of a string of alphanumeric characters. It is

sent to the modem to instruct it to perform the commands specified by

the characters.

As the list of AT commands supported ocassionally changes, it is wise

to check the latest listing with Sony Ericsson before starting any

software development (see “Service and Support”, page 9).
