Notes:
 In DisConnMode (Disconnect Mode), when Modem Control In is not
asserted, this condition either drops the connection or is ignored.
 All bit positions in the table that are blank represent “don’t care” bits for that
particular option, which can be set to either a 0 or 1 value.

(1) The Telnet Com Port Control feature is used in conjunction with Com Port Redirector. The
UDS2100 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 is detected, the connection is dropped. Both Telnet Com Port
Cntrl and Disconnect with EOT must be enabled for Disconnect with EOT to function
properly. Ctrl+D is only detected going from the serial port to the network.
(6) When Modem Control In transitions from a high state to a low state, the network
connection to or from the serial port drops.
Flush Mode (Buffer Flushing)
Using this parameter, you can control line handling and network buffers with
connection startup and disconnect. The default setting is 00.
FlushMode (00) ? _
You can also select between two different packing algorithms.
Note: All bit positions in the table that are blank represent “don’t care” bits
for that particular option, which can be set to either a 0 or 1 value.
