+iIATO - Inactivity Timeout
Syntax: AT+iIATO=n
Permanently sets maximum inactivity timeout in seconds to
signal socket disconnection in SerialNET mode. When signaled,
W24 will close the connected SerialNET communication socket.
In a modem environment, the W24 will also go offline following
this event.
When W24 is in iRouter mode and TUP< >2, if no activity is
detected for the specified period, W24 will disconnect its modem
side and go offline.
Parameters: n = number of seconds of inactivity, on a connected SerialNET
socket, to signal socket disconnection.
In iRouter mode, this number specifies a period of no activity on
either the WiFi or modem/cellular side.
Command Options:
n = 0 .. 65535
When W24 is in Server SerialNET mode (LPRT defined) and it
goes online in response to a triggering event: RING signal, MSEL
signal pulled low or AT+I!SNMD -- timeout calculation
commences only after the W24 opens the Listen port. When the
Web server is activated (using AWS=1), an external reference to
the Web server will restart the IATO timeout calculation.
Default: 0 - No timeout limit.
Result Code:
I/OK If n is within limits.
I/ERROR Otherwise.
AT+iIATO? Report the current inactivity timeout in seconds to signal socket
disconnection in SerialNET mode. The reply is followed by
I/OK.
AT+iIATO=? Returns the message "0-65535". The reply is followed by I/OK.
