Set Up Backup Connection Settings Dialog Box

How do I get to this dialog box?

  1. Open a 3270 terminal session.

  2. Open the Settings window.

    The steps depend on your user interface mode.

    User interface mode Steps
    Ribbon or InfoConnect Browser With a session open, from the Quick Access Toolbar, click .
    TouchUX With a session open, tap the Gear icon and then select Document Settings.
    Classic MDI With a session open, go to Options > Settings.

  3. Under Host Connection, select Set Up Backup Connection Settings.

From this dialog box, you can specify the settings for one or more backup TN3270 connections. If your primary connection fails, these connections will be tried next, in the order they are listed.

Backup Hosts

Add a host to the Backup Host list by clicking the Add button. When you enter more than one backup host, the connection options for each host are listed on a separate line. Use the Move Up and Move Down buttons to change the order in which the hosts are tried.

Options

Setting Description
Host Name/IP Address Identify the host to which you will connect. Type the host name, alias, or numeric IP address.
Note: Both IPv4 addresses (in the form 127.0.0.1) and IPv6 addresses (in the form 2001:0db8:3c4d:0015:0000:0000:abcd:ef12) are accepted.
Port Type the host port or socket number that the session should use. This field accepts any number between 0 and 66,535 (default = 23).
Device name Specify a particular LU or pool of LUs (up to 32 characters) on the host. If no device name is entered, the server connects to any available LU at the specified port.
Security Settings Secure data communications with SOCKS or SSL/TLS.
Use Telnet Extended If selected, enables TN3270E protocols when supported.

Text Display
**Terminal/Device type ** Specify the model of the terminal or device type emulated by this session.

You can select a value from the drop-down box, or type a value that is not listed. This allows you to specify a terminal model that is not implicitly supported but might work, such as Fujitsu.

In most cases you should leave this setting at the default value. If you choose any other value, be sure to use a string that is acceptable to the host; otherwise, you may experience problems connecting to the host, and emulation problems after connecting to the host. Typically, these types of problems occur if the host is not configured to recognize the terminal specified.
**Model ID ** Specify the model of the terminal or device type emulated by this session.

If the string specified in Terminal/Device type includes &M, the &M is replaced with the model number from this list when the string is sent to the host. For example, if IBM-3279-&M is specified and Model 3 is selected here, the string sent to the host is IBM-3279-3.

Selecting an Extended model allows the host to specify a greater number of colors (seven instead of four) and a wider variety of display attributes. Any Model allows the gateway or mainframe to determine which model ID to use.

Each model is associated with a terminal window display of a specific size (e.g., 24 rows by 80 columns). To specify a different number of rows or columns, select \<Custom Model Extended>. When Model ID is set to \<Custom Model Extended>, Terminal/Device type changes to IBM-DYNAMIC.

The default value is Model 2 24x80 Extended.
**Rows ** The number of rows to use in the terminal window display. The valid range is 24 - 255. If the host application specifies a particular screen size, this value may be ignored.
**Columns ** The number of columns to use in the terminal window display. The valid range is 80 - 255. If the host application specifies a particular screen size, this value may be ignored.

Graphics Display
**Enable graphics ** When selected, enables this session to emulate a graphics terminal. This allows you to run any host application that uses the IBM Graphics Data Display Manager (GDDM) library, such as SAS or ImageView.
**Model ID ** WhenEnable graphics is selected, specifies the type of graphics terminal emulated by this session.

Security
**Security Settings ** Secure data communications with SOCKS or SSL/TLS.
