Disconnect Mode
This option determines the conditions under which the unit causes a network
connection to terminate. In DisConnMode, DTR drop either drops the connection or is
ignored.
Note: To look up hex values, see B: Binary to Hexadecimal.

1. The UDS sends 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 closes 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
turns off instead of blinking.
5. When Ctrl D or Hex 04 are detected, the connection is dropped. Both Telnet
mode and Disconnect with EOT must be enabled for Disconnect with EOT to
function properly. Ctrl D is only be detected going from the serial port to the
network.
Flush Mode
Flush Mode (buffer flushing) controls line handling and network buffers with
connection startup and disconnect. You can select between two different packing
algorithms.
Note: To look up hex values, see B: Binary to Hexadecimal.
