Netgear 771S AT Command Reference - Page 7

1: About This Guide 1 Introduction This document describes supported standard and proprietary AT commands available for NETGEAR AirCard™ devices, and provides details where commands vary from the standards. These commands are intended for use by OEMs, and are supplemental to the standard AT commands for GSM devices defined by the 3GPP (3rd Generation Partnership Project) in TS 27.007 AT command set for User Equipment (UE) and TS 27.005 Use of Data Terminal Equipment- Data Circuit terminating Equipment (DTE-DCE) interface for Short Message Service (SMS) and Cell Broadcast Service (BSE). Note: When designing applications that use these AT commands, use NETGEAR Watcher® or other NETGEAR applications as functionality templates to ensure proper use of command groups. For questions or concerns relating to command implementation, please contact your NETGEAR account representative. Command access Most commands in this reference are password-protected. To use these commands, you must enter the correct password using AT!ENTERCND on page 14. Once the password is entered, all commands are available and remain available until the modem is reset or powered off and on. Command timing Interval timing Some commands require time to process before additional commands are entered. For example, the modem returns OK when it receives AT!DAFTMACT. If AT!DASBAND is received too soon after this, the modem returns an error. When building automated test scripts, ensure that sufficient delays are embedded, where necessary, to avoid these errors. Escape sequence guard time The AT escape sequence "+++" requires a guard time of 1.0 seconds before and after it is used. Rev. 1 Sep.13 Proprietary and Confidential 7
