APPENDIX A : AT Command Set
At any given time the WINC 2400C configuration port is in the command mode. The configuration
port accepts AT commands from the host computer connected to that port. These commands are sent
to the WINC 2400C as character strings composed of printable ASCII characters. Using the same
character set, the WINC 2400C responds to the host computer's command by sending back a result
code string indicating whether the WINC 2400C was able to accomplish the requested command.
The command language is simulated to the Hayes compatible and de facto industry standard AT
command set. In addition to the basic AT commands, certain command extensions accommodate
specific WINC 2400C configuration requirements.
AT Command Syntax
A command line is a string of characters sent from the host computer or peripheral - Data Terminal
Equipment (DTE), to the WINC 2400C - Data Communications Equipment (DCE). (The command
line is interpreted by the DCE only when in the command state.) All command lines have a prefix, a
body, and a terminator. The prefix consists of the characters "AT" and the body is a command string
restricted to the printable ASCII characters. The default terminator is the
required for all commands.
Commonly used AT Commands with the WINC 2400C
Viewing the Current Connection Status
The current connection status of the WINC 2400C can be viewed at any time by using the AT&&
command. In response to this command, the connection status of WINC 2400C will be displayed as
following.
