Technical reference section
26.2.96
This section describes the standard AT commands that allow you to configure your
GSM module. These commands are grouped according to subject area.
When you receive data that is reproduced on the screen (data echo), the text is usually
shifted upward when the edge of the screen is reached. When you generate screen
outputs using AT commands (e.g. AT&V), a maximum of 30 lines is displayed for each
command. If, for example, you enter the AT&V command several times on the same
line (AT&V&V&V), a maximum of 30 lines is displayed.
The ATEn command affects the echo of characters that the GSM module receives from
your computer when the GSM module is in command mode.
The ATQn command allows you to control the transmission of result codes as acknowl-
edgments to AT commands (e.g. OK, ERROR, RING).
