5.10.3 Configure Connection Settings Dialog Box

Getting there

Open a 3270 terminal session.

The steps depend on your user interface mode.

User Interface Mode	Steps
Ribbon or Reflection Browser	With a session open in Reflection, from the Quick Access Toolbar, click .
TouchUx	Tap the Gear icon and then select Document Settings.

Under Host Connection, click Configure Connection Settings.

From this dialog box, you can specify the settings for a TN3270 connection.

Connection

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.

Host Connection Options

Use Telnet Extended	If selected, enables TN3270E protocols when supported.
Automatically connect to the host	Select to establish a host connection as soon as the associated session document is opened.
When connection is terminated	Specify options for reconnecting after any disconnection that is not initiated from Reflection.
	Choose	To have Reflection...
	Reconnect automatically	Attempt to reestablish the connection.
	Prompt for reconnection	Prompt whether to attempt to reestablish the connection. (When No is selected, the session is left open and disconnected.)
	Leave disconnected	Leave the session disconnected with the session open.
	Close session automatically	Close the session.

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

When Enable graphics is selected, specifies the type of graphics terminal emulated by this session.
