Configuring the Unit
4.6.8 DisConnMode
This determines the conditions under which the unit will cause a network connection to
terminate.
In DisConnMode (Disconnect Mode), DTR drop either drops the connection or is ignored.

1. The XPort™ will send the "Terminal Type" upon an outgoing connection.
2. A password is required for a connection to the serial port from the network.
3. The TCP connection will close even if the remote site does not acknowledge the disconnection.
4. When there is a network connection to or from the serial port, the state LED will turn off instead of blink.
5. When Ctrl D or Hex 04 is detected, the connection is dropped. Both Telnet mode and Disconnect with EOT must be enabled
for Disconnect with EOT to function properly. Ctrl D will only be detected going from the serial port to the network.
6. When DTR transitions from a high state to a low state, then the network connection to or from the serial port will drop.
4.6.9 Flush Mode (Buffer Flushing)
Using this parameter, you can control line handling and network buffers with connection
startup and disconnect. You can also select between two different packing algorithms.
