5.3.1 AT Commands
When using a terminal application, you will need to manually type in each
command.
 For most commands, when you are entering them using a terminal
connection, you will need to preface the command with AT (exceptions are
noted), that is,
ATA which is listed as A.
 Some commands have specific parameters while other commands will take
whatever you type.
 Required variable parameters are denoted with italicized text, example, Dn.
The n is variable.
 Acceptable parameters and/or specific formats are listed with each
command.
 Most commands with parameters can be entered with ? to read the current
value (for example,
AT&D? will respond with "2" if the default has not been
changed).
 Optional parameters are denoted with square brackets [ ].
 AT Commands are not case sensitive. A capital "E" is the same as a lower-
case "e".
 When you are using a terminal connection, if you enter a command which is
recognized by the RLXIC-EH, it will respond with "OK". If the command is not
recognized, the response will be "ERROR".
 Those commands applicable only to certain model numbers of the RLXIC-EH
will be noted.
Caution: Symbols listed with commands, such as *, /, &, or ?, are part of the command and must
be included. Commands with symbols other than * may require PassThru mode.
