Parameter

Command

Description

Echo control

ATEn

If n=0, commands are not echoed.

 

 

If n=1, subsequent commands will be echoed.

 

 

The default, upon unit reset, is for no echo (ATE0).

 

 

 

Disconnect

ATHn

If n=0, any connection to a remote host is dropped.

 

 

Other value of n is ignored.

Return to data mode

ATOn

Exits command mode and places the serial port in the

 

 

data mode.

 

 

All subsequent data is sent to the network application, if

 

 

connected, until an enter command mode sequence is

 

 

received. Any value of n is ignored, if present.

Quiet mode

ATQn

If n = 1, no result codes are returned.

 

 

If n = 0, result codes are returned to the local device.

 

 

0 is the reset default value.

Verbose mode

ATVn

If n = 0 and not in quiet mode, result codes are

 

 

returned in numerical form.

 

 

If n = 1, results are returned as text. 1 is the reset

 

 

default value.

Table 6 Extended AT Commands

Parameter

Command

Description

Console pass through

AT#C<string>

Passes the string to the server configuration console.

 

 

The string can be any valid console command. Refer

 

 

to your server documentation for console commands

 

 

available on your unit.

 

 

Since this command does not follow the normal AT

 

 

command format of <command><number>, it must

 

 

be the last command on the line unless the next

 

 

command is a '#' command. All characters up to the

 

 

end of line or a '# will be considered part of the

 

 

console command.

 

 

If console quiet mode is not is enabled, then the

 

 

response will be the standard console task response.

 

 

Example:

 

 

AT#Cset nw ssid silex#Csave

Console Quiet mode

AT#Qn

If n = 0, a response to a #C command is given.

 

 

If n = 1, the response is not provided. The default

 

 

after reset is 1.
