On XBee Cellular in API mode how do I tell if remote side closed TCP connection?

It seems like the last thing I get is an RX packet.

The transmit status frame should provide you with that data in the Status byte.

Yes, however I'm not transmitting.  Sorry if the question was unclear.  I open a connection,  send some data, the remote side sends some data and then eventually closes.  How would one detect the (remote) close?   

Apparently you cannot - as I've verified with email support.  However I am experimenting with emitting an empty send to "poll" the connection to see if the send gets a "remote closed" error reliably.

No it does not have an option for that.
