Chapter 2: AT+i Commands Reference
May 31, 2008 AT+i Commands Reference Manual 2-117
port=<portnum> Listening port to be used by a remote system when connecting to
the W24 Family in order to send AT+i commands over the
Internet.
The listening socket will accept one remote connect request.
When a remote system connects through the listen socket, W24
will disable its local host serial port and spawn a new TCP/IP
socket, ready to receive AT+i commands. AT+i response strings
will be transmitted back to the same socket.
When the connected socket is closed, the local host serial port
will be re-enabled and the listen socket will be ready to accept a
new connection. The remote end may also issue the AT+iDOWN
command to force W24 to disconnect and reboot.
Default: 0 (Disabled).
Result Code:
I/OK Upon successfully opening the remote AT+i service TCP/IP
listening socket.
I/ERROR Otherwise.
AT+iLATI~n Temporarily set the remote AT+i service Listen port. The
permanent value will be restored after completing the next
session, both if the session was successful or not.
AT+iLATI? Returns current AT+i service listening port number followed by
I/OK.
AT+iLATI=? Returns the message "0-65535" followed by I/OK.
