61. IntroductionComputers use AT commands to communicate with modems, i.e. you can use the commands described in this booklet to use data connections via your PremiCell terminal. Most communications ap-plications, however, have a user-friendly interface that hides these AT commands from the user.

The AT commands supported by the data adapter are listed below according to their uses. A short description, the syntax, the possible setting values and responses of the AT commands are presented. Note that the AT or at prefix must be included at the beginning of each command line. You may type several AT commands on the same line, and in such cases you need to type the AT or at prefix only at the beginning of the command line. Soported by all Nokia products. Giving a command whichresponse, and if the extended errorwith the AT+CMEE command, the the command is not supported with thrameters may not be supported bythose parameters are just ignored sponses.

2. Descriptions of AT Commands

2.1. Call Control

ATA Answer CommandThis command answers an incoming call. The call is indicated by the RING or +CRING message on the terminal equipment or by the number 2 if numeric mode has been selected. Syntax:

ATA Answer incoming call.

ATD Dial CommandThis command initiates a call. When a call is initiated, the command must contain the called party's number or a directory entry which contains the stored number.
