Chapter 9: Setup Mode: Channel Configuration

Remote Port

You must set the remote TCP port number for the unit to make outgoing connections. This parameter defines the port number on the target host to which a connection is attempted.

Remote Port ( 0) ? _

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).

Note: This option does not display when Hostlist is enabled from the ConnectMode prompt (see Connect Mode on page 72 for more information).

DisConnMode

This setting determines the conditions under which the unit will cause a network connection to terminate.

DisConnMode ( 0) ? _

Notes:

In DisConnMode (Disconnect Mode), DTR drop either drops the connection or is ignored.

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.

(1)The XPress DR+ 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.
