4: Using Setup Mode for Configuration
XPort™ User Guide 34
Note: To connect an ASCII terminal to a host using the unit for login
purposes, use the remote port number 23 (Internet standard port number for
Telnet services).
DisConnMode
This setting determines the conditions under which the unit will cause a network
connection to terminate.
Note: In DisConnMode (Disconnect Mode), DTR drop either drops the
connection or is ignored.

(1) The XPort 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 mode 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 DTR 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. You can also select between two different
packing algorithms.
