exists in White List and the message password matches with the password specified in the White List.
One blank entry is shown by default and you can add or delete an entry by pressing the "+" or "–" button. The White List numbers and
passwords can be cleared by pressing the "Delete" button.
To add an entry, simply enter the appropriate phone number and password and click "Save".

Security

In order to provide security for SMS command execution, it is recommended that all SMS commands be subject to successful
authentication against the White List as well as setting a password for each phone number entered.
This prevents unauthorised or accidental execution of SMS commands.

Replies

Upon receipt of successfully formatted, authenticated (if required) command, the router will reply to the SMS in the following format:
Type
Get Command
Set Command
Execute Command
Where "VARIABLENAME" is the name of the value to be read
Where "VARIABLENAME(x)" is the name of another value to be read
Where "VALUE" is the content to be written to the "VARIABLENAME"
Where "COMMAND" is a supported command to be executed by the device (e.g reboot)
Where "PASSWORD" is the password (if configured) for the corresponding sender number specified in the White List
Multiple commands can be sent in the same message, if separated by a semicolon.
For Example:
get VARIABLENAME1; get VARIABLENAME2; get VARIABLENAME3
PASSWORD get VARIABLENAME1; get VARIABLENAME2
set VARIABLENAME=VALUE1 ; set VARIABLENAME2=VALUE2
PASSWORD set VARIABLENAME1=VALUE1; set VARIABLENAME2=VALUE2; set VARIABLENAME3=VALUE3
If required, values can also be bound by an apostrophe, double apostrophe or back tick.
For Example:
"set VARIABLE='VALUE'"
"set VARIABLE="VALUE""
