Thin Client

PowerTerm WebConnect Client-Server model consists of a thin PowerTerm WebConnect client and server. The Thin Client provides the terminal emulation window when the server supplies the connectivity to the host.

Starting the PowerTerm WebConnect Java Client

The PowerTerm WebConnect Server must be up and running before the user can start the client.

To start the PowerTerm WebConnect Java Client:

  1. Open your web browser.

  2. Type the address provided by your administrator.

(i.e. http://admin/Ericom/PowerTermWebConnect/Secure/PTJavaClient.html)

The Security Warning dialog box appears:

  1. Click Yes. The Java Client main screen and the Login dialog are displayed.

  2. Type in the User Name and Password.

  3. Click Login. The Connect dialog is displayed.

User Name: Specifies the user name defined by Administrator.

Password: Specifies the user's password defined by Administrator.

 

What is a Host connection?

Besides a physical connection between one's computer and the host, an emulation software like PowerTerm is also required. The user must define certain critical parameters (i.e. host name, session type and terminal type) in the Connect dialog box which will instruct PowerTerm how to emulate the host.

Many large organization have access to multiple hosts. Not all users are authorized to access all the host systems. .

 

Connection Privileges

The system administrator determines which users are privileged to access which host connections.

Consequently, the user will be able to connect:

 

Logging In

  1. Choose Connection|Log in. The Login dialog box is displayed.

  2. Type in the user name and password provided by the administrator.

  3. Click Login. In the case of a successful login the Connect dialog appears.

Otherwise the PowerTerm WebConnect Server message will be received with cause of failure.

Examples of possible error messages:

  • The User "user-name" is not defined;

  • Invalid password;

  • The access of user "user-name" to PowerTerm WebConnect Server is denied. Please contact your System Administrator (in the case of an existing restriction for this user's access in the PowerTerm WebConnect Server Database);

  • Exceeded quota (up to "number of concurrent sessions defined for this user" logins allowed).

User Name: Specifies the user name that will be relayed on to the host when attempting to log on.

Password: Specifies the user's password that will be relayed on to the host when attempting to log on.

 

Logging Off

  • Choose Connection|Log Off. The user is logged off from the host.

 

Connecting to a Pre-defined Connection

To connect to a pre-defined connection:

  1. Choose Connection|Connect. The Connect dialog box is displayed.

Note Only those host connections that are available to the user through his present group associations appear in the list.

  1. Choose the desired host connection from the list.

  2. Click Connect. The host connection is made.

Establishing a User Defined Connection

Note The administrator has determined (via the Administration Tool) which privileges to grant to each user or group of users. The user in this case has been granted the privelege to connect to any host.

To connect to any host:

1. Choose Connection|Connect. The Connect dialog is displayed.

2. Select the desired Terminal Type.

3. Select the Terminal Model.

4. Select the desired Connection Protocol.

5. Click Code Page if necessary and fill in the parameters.

6. Fill out the necessary Parameters based on your choice of emulation.

7. Click Connect. The connect to desired host is established.

Terminal Type: Changes the currently supported emulation.

Terminal Model: Determines the ID returned by the emulation program to the host. Make sure you select an ID that the host application recognizes.

Connection Protocol: Determines the communication protocol to be implemented in your host connection.

Code Page: Enables you to specify the mode of a keyboard. This sends the correct keystrokes for a country's or language's keyboard layout. For further explanation see Code Pages.

For more information see Connection Parameters

Pre-defined Connections with "Free User" Status

To connect to a host connection:

  1. Choose Connection|Connect. The Connect dialog is displayed.

  2. Choose the desired host connection from the list from the pre-defined connections or select Free Connection (and follow the instructions in Establishing a User Defined Connection).

  3. Click Connect. The desired emulation screen appears.

    Free User status (for Users Who Lack Pre-Defined Connections)

    The administrator must as a pre-requisite give you the privilege of "free user". A free user is able to use a pre-defined connection or to connect to any host as well.

    To connect to any host:

    1. Choose Connection|Connect. The Connect dialog is displayed.

    2. Type in the correct I.P. address in the HostName field.

    3. Select the desired terminal type.

    4. Select the terminal model.

    5. Select Use SSL between PowerTerm Server and Host if applicable. The SSL Type and Show SSL Certificate are enabled.

    a. Choose the appropriate SSL type.

    b. Select Show SSL Certificate if desired.

    6. Click Connect. The desired emulation screen appears.

    Host Name: Specifies a host to which to connect. This can be an Internet address, an Internet node name, or a name that can be resolved by a host's file or a domain name server.

    Terminal Type: Changes the currently supported emulation.

    Terminal Model: Determines the ID returned by the emulation program to the host. Make sure you select an ID that the host application recognizes.

    Choice of either one of the three fields depends on the emulation:

    Terminal Name(VT): Overrides the Terminal Model value returned by the emulation program to the host. Make sure you select an ID that the host application recognizes.

    LU Name(3270): Specifies a type of addressable unit in an SNA network.

    Device Name(5250): Specifies the device to connect to.

    Message Queue: Specifies to which AS/400 message queue exception messages should be sent. For example, the AS/400 may need to tell the printer to switch to another paper tray.(5250 only)

    Message Library: Specifies which library contains the message queue for exception messages.(5250 only)

    Use SSL between PowerTerm Server and Host: This field (which is related to above) determines whether to implement the SSL protocol between the server and the host.

    SSL Type: Specifies the SSL protocol being implemented.

    Show SSL Certificate: Determines whether to display to the user the SSL Certificate provided by the host.

    Disconnecting from Remote Host

    • Choose Connection|Disconnect. The emulation session is disconnected from the host.

    Note You can reconnect to the same host with the same connection properties after you have disconnected.

    Reconnecting to Remote Host

    • Choose Connection|Reconnect. The session is reconnected to host.

      Working Offline

      • Choose Connection|Offline.

      Note This option is enabled for VT emulation only.

      Displaying SSL Certificate (from PowerTerm)

      The user is able to confirm that the connection from the host is secure. Every SSL connection can be defined whether or not to display the SSL Certificate. Upon the displaying of the certificate the user can decide to accept or reject the connection.

      Creating Multiple Sessions

      The user is able to work simultaneously with multiple sessions with different hosts.

      Choose Connection|New Session option. The new emulation screen with Login dialog is displayed.

      NRC Set:Determines the communication and keyboard character set. This is a 7-bit character set within which a number of the less commonly used symbols (such as and @) are replaced by national characters. Different countries use different variants of this character set. For example, Germany replaces the \ with <0 with an umlaut V>, while France replaces the same character with <c with a tail g>. Each country therefore has its own NRC.

      UPS Set: Determines the communication and keyboard character set for 8-Bit data only. Select one of the available languages. You can assign the supplemental character set you use most often as a special standby set. This standby set is called the user-preferred supplemental set (UPS Set). This feature provides applications with an easy way to access the user's preferred supplemental set.

      8 bit Controls (only for UPS Set value "Code Page xxx"): If the communicated data is in 8-bit character format, check this parameter. For 7-bit characters, clear this parameter. If this parameter is cleared, the 8th bit is truncated.

      If you receive 7-bit data, you can convert it to 8-bit data for printing on the slave printer.
