C: AT Commands

•Response Codes

•Modem Signal Behavior

• Phone Numbers

In addition to the web‐based interface, you can use some typed

• Port Settings

AT Commands with the RJ‐11 IP Gateway. To enter AT

 

commands, you need to be connected to the device via telnet

 

or by using the RJ‐11 port as you would a standard analog

 

modem.

 

All AT command strings, with the exception of the break

 

sequence (“+++”) and the repeat command (“A/”), must be

 

terminated with the command line termination character,

 

defined in S3 (default is CR). All characters before ʹATʹ are

 

ignored. Unsupported commands are ignored and generate an

 

“OK” result code. Multiple commands may be combined on a

 

single line, however the AT command string is currently

 

limited to 40 characters.
