33.3.13 +iLATI — TCP/IP Listening Socket to Service Remote AT+i
Commands
Syntax: AT+iLATI=
Sets the Remote AT+i service listening port number. When
connected to the Internet, opens a TCP/IP listen socket on
the local IP address and the specified port.
Parameters: port=0..65535
Command Options:
port=0 Remote AT+i service disabled
port= Listening port to be used by a remote system when
connecting to the iChip 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, iChip 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 iChip to disconnect
and reboot.
Default: 0 (Disabled)
Result Code:

followed by I/OK.
