AT commands
The following most used AT commands are explained in this manual. Other AT commands not mentioned
here may still be supported.
Syntax conventions
Syntax definitions use the following conventions:
<parm> indicates that a parameter (without < and >) can be filled in by the user.
{ <opt1> | <opt2> | … | NA } indicates that one of various options must be chosen by the
user. NA means no value is defined.
[<options>] indicates that <options> may or may not be included in the command.
String parameters must be enclosed in double-quotes (ASCII 34) and numeric parameters
must not be. Only the ASCII double-quote is recognized; slanted quotes, e.g. from the
Windows-1252 or UTF-8 character sets, are not valid.
Keywords and parameters are separated by commas.
The command name and all keywords must be in upper case; most user-provided
parameters are case sensitive but may be either case.
TE means Terminal Equipment - the equipment connected locally to the EXPLORER 540.
