8. 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 GT47 to instruct it to perform the commands specified by the
characters.
As the list of AT commands supported occasionally changes, it is wise to
check the latest listing with Sony Ericsson before starting any software
development (see
“Service and Support”, page 9).
The AT commands listed below are supported by the GR47/48 (italic)
within the GT47. Be aware that not all AT commands will perform valid
operations in the GT47 owing to its modified range of IOs.
