6: Line and Tunnel Settings
XPort AR User Guide 37
The XPort AR supports two connections simultaneously per serial port. One of the connections is
Connect Mode and the other connection is Accept Mode. The connections on one serial port are
separate from those on the other serial port.
 Connect Mode—Makes an active connection. The receiving node on the network must listen
for the Connect Mode connection. Connect Mode is disabled by default.
 Accept Mode—Listens for a connection. A node on the network initiates the connection.
Accept Mode is enabled by default.
 Disconnect Mode—Defines how an open connection stops the forwarding of data. The specific
parameters to stop the connection are configurable. Once a defined event occurs, the XPort
AR disconnects Accept Mode and Connect Mode connections on that port.
You can view statistics and configure two tunnels by using the Tunnel web page. When you click
Tunnel from the Main Menu, Tunnel 1 fields display. To go to Tunnel 2, click the Tunnel 2 button.
There are six sub-menus that you can use as follows:
 Statistics—Displays statistics for the two lines. For example, completed accepts, completed
connects, disconnects, dropped accepts, dropped connects, etc.
 Serial Settings—Configures buffer size and DTR.
 Connect Mode—Controls how a tunnel behaves when a connection attempt originates
locally.
 Accept Mode—Controls how a tunnel behaves when a connection attempt originates from the
network.
 Disconnect Mode—Relates to the disconnect of a tunnel.
 Packing Mode—Sends packed data that is queued in larger chunks instead of sending it
immediately after being read on the serial line.
 Modem Emulation—Initiates and accepts tunnel connections using the AT commands.
Tunnel Statistics
The XPort AR logs tunneling statistics. The Dropped statistic shows connections ended by the
remote location. The Disconnects statistic shows connections ended by the XPort AR.
To display the tunnel statistics, perform the following steps.
