Configure basic connection properties

You can configure the basic connection properties such as host, terminal type, port, code page, and screen size.

To configure the basic connection properties:


Procedure

  1. From the toolbar, click icon to open a connection properties file, and select a connection configuration (.comm) file to connect to the host.

  2. Type the name or IP address of the host computer.

  3. Configure the terminal type:

    1. Select the type of terminal emulation connection to use: TN3270, TN3270E, TN5250, VT default, VT100, VT420-7, VT420-8 or VT UTF8. 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 provides connections to a UNIX-like system. The default is TN3270.

      Communications Server for z/OS® 1.2 and later introduced a new function called contention resolution. This new function 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 endless loop conditions when you try to connect to a z/OS host. The default setting for the HOD layer is to request RFC 2355 Contention Resolution. If you experience such problems, configure the HOD layer so that it does not request RFC 2355 Contention Resolution.

    2. Optional: Click Advanced to change the contention resolution setting. Scroll down the properties in the Configure optional advanced settings list. Change the setting of negotiateCResolution to false. This applies to the TN3270E terminal only.

    3. Type the name of the specific Workstation ID on the host. This field is available only if you are using TN5250 terminal emulation. Leave this field blank if you are not sure about the Workstation ID to connect to.

    4. Type the name of the specific logical unit (LU) or LU pool on the host. This field is available only if you are using TN3270 Enhanced (TN3270E) terminal emulation. Leave this field blank if you are not sure about the LU to connect.

  4. Type the port number on which the host is configured.

  5. Select the code page that corresponds to the language that you are using. The default is 037 - United States.

  6. Select the number of horizontal and vertical characters that can be displayed in the screen size. The default is 24x80.
