1. The SDS 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 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 will only be detected going from the serial port to
the network.

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

Pack Control

Two firmware-selectable packing algorithms define how and when packets are sent
to the network. The standard algorithm is optimized for applications in which the unit
is used in a local environment, allowing for very small delays for single characters
while keeping the packet count low. The alternate packing algorithm minimizes the
