Use the Connection Setup command on the Connection menu to open the Connection Setup dialog box, from which you can specify connection options.

This dialog box is not available if it is disabled in the profile associated with this session.

Host

Use this box to identify the host to which you wish to make a connection. You can use a full host name, or its full Internet Protocol (IP) address. The host name is resolved by the hosts file on your local machine or by a domain name server on your network. If you have no domain name server on the local network and don't use a hosts file, you will need to specify the full IP address of the host (for example, 124.24.36.85).

If you are not connecting with the default port, use the format Host:Port to specify an alternate port.

Protocol

The Protocol specifies how Reflection communicates with the host. To establish a host connection, both Reflection and the host computer must use the same network protocol.

The available values are:

TN3270E    TN3270E, or Telnet Extended, is for users of TCP/IP software who connect to their IBM mainframe through a Telnet gateway that implements RFC 1647. Such gateways, like the Apertus DataCenter Hub gateway, support the TN3270E protocol, which allows you to specify the connection device name (also known as LU name), and provides standard support for the ATTN key, the SYSREQ key, and SNA response handling.

If you try to use Telnet Extended to connect to a gateway that doesn't support this protocol, Reflection will use standard TN3270 instead.

When you select TN3270E in the Protocol list, complete the following options:

Specify Host LU name

    Specify the name of the host LU (logical unit) to use when the session connects to the host. (The host LU is also known as the device name or the pool.) If no host LU is specified for the session and the Prompt if not specified option below is not selected, the host dynamically assigns one to the session.
Prompt if not specified     Reflection will prompt the user to supply a unique LU name when none is provided. Select this option to avoid excessive waiting time if a server cycles through a large number of LUs on the host before selecting one that is appropriate.

Generate unique name     Reflection generates a unique host LU name when a connection to the host is initiated. The name is based on the full name of the user's computer. If the computer name cannot be found, the IP address is used.


Use TN association

    The TN association option links a 3270 terminal session with a specific 3270 printer session. When associating a 3270 terminal session with a 3270 printer session, you must first enter a unique TN association string in the Advanced Settings dialog box in Connection Setup for the 3270 terminal session; once a TN association string for a 3270 terminal session exists, you can select it from the Use TN association box when configuring a 3270 printer session. For step-by-step information, go to Using TN Association.

Use ID Manager     ID Manager provides IDs to client applications at runtime. An ID is connection data that is unique for an individual session with a host. Administrator privileges are required to configure ID Manager.

Click Advanced to configure additional TN3270E settings.
TN3287    TN3287 is for users of TCP/IP software who connect to their IBM mainframe through a Telnet gateway that implements RFC 1646.

When you select TN3287 in the Protocol list, complete the following options:

Specify device name

    Specify the name of the device name to use when the session connects to the host. (The device name is also known as the host LU or the pool.) If no device name is specified for the session, the host dynamically assigns one to the session.

Prompt if not specified     Reflection will prompt the user to supply a unique device name when a connection is requested.



Generate unique name     When this option is selected and no device name is specified in the configuration file or the Connection Setup dialog box, Reflection generates a unique device name when a connection to the host is initiated. The name is based on the full name of the user's computer. If the computer name cannot be found, the IP address is used.


Use ID Manager     ID Manager provides IDs to client applications at runtime. An ID is connection data that is unique for an individual session with a host. Administrator privileges are required to configure ID Manager.
Click Advanced to configure additional TN3287 settings.
Playback

    This transport is used to play back event traces. For information about event traces, see Trace.

When you select Playback in the Protocol list, complete the following Playback settings:

URL

    Specify the URL of the trace file or click Browse to open a dialog box where you can search for the URL to use.

Pause during playback

    Specify whether to pause for user input during playback of the trace file.

SSL/TLS

Click to open the SSL/TLS Settings dialog box, where you can specify SSL/TLS and security proxy server settings.

IP mode

Select Use IPv4 or Use IPv6 to force resolution of a host name using the selected IP addressing mode before connecting. The option Use default connects without performing this resolution. If IPv4 or IPv6 is used, it is displayed in the host URL status area.

Reconnect when host terminates connection

If you select this option, Reflection attempts to reconnect as soon as the host connection is terminated by the host.

Connect at startup

Select this option if you want Reflection to establish a host connection as soon as Reflection is opened.

Once you've set the options in this dialog box, click Connect to connect immediately, or click OK to close the dialog box. This option is selected by default.
