Basic connection properties

Basic Connection Properties include the following information:

Connection Configuration
Specify the name of the Connection Configuration (.conn) file you want to use to connect to the host. For additional information on configuration files , see Creating a new connection configuration file.
Host
Type the name or IP address of the host machine.
Terminal type
  1. Select the type of terminal emulation connection to use: TN3270, TN3270E, TN5250 or a VT terminal type. Typically, TN3270 terminal emulation provides connections to an IBM® zSeries® (System 390) host. TN5250 terminal emulation typically provides connections to an iSeries™ (AS/400®) host. VT terminal emulation typically provides connections to a UNIX-like system.

    The default is TN3270.

    Note: Communications Server for z/OS® 1.2 and later introduced a new function called Contention Resolution. This new functionality on the client side was introduced in Host On-Demand 7.0.2. If you do not have the latest maintenance levels for Communications Server for z/OS, you might experience COMM655 errors or other hang conditions when trying to connect to a z/OS host.

    The default setting for the HOD layer is to request RFC 2355 Contention Resolution. If you experience these problems, you need to configure the HOD layer to not request RFC 2355 Contention Resolution.

    To change the setting, open the Advanced Settings window by selecting the Advanced button on the IBM Extension for Terminal Based Applications window. Scroll down through the properties in the Configure optional advanced settings list until you come to negotiateCResolution. Change the setting for this property from true to false.

    This applies only to the TN3270E terminal.

  2. Type the name of the specific Workstation ID on the host that you want to connect to, if any. If you are not sure what Workstation ID to connect to, leave this field blank. This field is available only if you are using TN5250 terminal emulation.
  3. Type the name of the specific logical unit (LU) or LU pool on the host that you want to connect to, if any. If you are not sure what LU to connect to, leave this field blank. This field is available only if you are using TN3270 Enhanced (TN3270E) terminal emulation.
Port
Specify the port number on which, the specified host is listening.
Code page
Specify the code page that corresponds to the language you are using. The default is 037 - United States.
Screen size
Specify the number of horizontal and vertical characters that can be displayed. The default is 24x80.
