32. Tips

1. What is TN3270 usage purpose?
TN3270 allows a Chameleon PC to access an IBM host. That host has to be running an appropriate implementation of or workstation users, to gain access to a host system and to display data on their screens. It is a remote terminal service. Your PC cannot be a Mainframe. We provide a Telnet 3270 client only.

2. Who uses TN3270?
People who need a terminal emulation for IBM mainframe based application.

3. Which default port is used for a TN3270 connection?
Port 23 is the well known port for a Telnet connection to IBM Mainframe, using TN3270 emulation. The Mainframe Telnet server may listen on a different port such as: 1001, for example. In this case, port 1001 is to be defined in the Connection port option.

4. What is a ‘Model’ type?
The model type relates to the dimensions of the terminal screen. For example: 2 - Model 2 (24x80) -> the default terminal size is 24 lines and 80 columns.

5. What is IBM ‘IND$’ Protocol?
The IND$ program is designed with ease-of-use and efficiency in mind, all file transfer services are presented in a set of easy-to-use panels that let users point and click to set file transfer parameters and options. When special settings are required to set the type of file transfer or unique data formatting requirements, 3270Vision not only allows users to quickly set these parameters but also to build a library of file transfer templates for later use. Utilizing these templates, execution of complex transfers is as easy as point and click.

6. What does ‘EBCDIC’ mean?
EBCDIC is the IBM character storage format. Meaning that when connecting to an IBM Mainframe from your PC station, TN3270 uses a conversion table allowing to translate Windows/DOS based characters sets (ANSI/ASCII) to EBCDIC format, and vice versa.

7. What are IBM Mainframe operating systems?
MVS, CMS,VM and TSO.

8. What is a PU?
Control Unit - usually refers to the unit interpreting between the Terminal and the CPU. The Physical Unit (PU) is responsible for the operation of the physical data links attached to a node.

9. What is an LU?
Logical Unit - usually refers to the terminal itself.

10. NW4SAA: What is a ‘Server Name’?
Name of the Netware for SAA server you are trying to connect to. If you are using TCP/IP protocol as a transport, you may enter the IP address of the server or its TCP/IP name.

11. NW4SAA: What is a ‘Service Name’?
Profile Name of the NetWare for SAA server, allowing you to connect specific host. If not defined, you will be prompted to a window listing all profiles (to all hosts).

12. What is a Connection Profile?
The connection profile is created through the "connection profile" dialog and contains as many connection profiles as you need. The connection profile lets the user to automatically connect to a pre-defined Host with specific connection information. All the connection profiles are stored in the TN3270 configuration file: TN3270.CFG.

13. What is SAP?
Service Access Point: You need to consult the System Administrator for the appropriate number.

14. How many ‘Model’ types are available in TN3270?

• 2 - Model 2 (24x80)
• 3 - Model 3 (32x80)
• 4 - Model 4 (43x80)
• 5 - Model 5 (27x132)

15. What are ‘Copy and Paste’ options for?
The Copy and Past option are mainly used for copying and pasting information to spreadsheets. In versions prior to 4.5, copying in block mode was possible, but pasting was in line mode by default. In order to paste in block mode prior to 4.5 (i.e. in a single column of fields) you needed at least TN3270 4.01.1, and you must manually enter the following into the [Terminal] section of your TN3270.CFG file: Paste=Rectangle

16. How can I transfer files from my PC to my IBM Mainframe, and vice versa?
There is a File Transfer Setup dialog box under the Settings menu. This box lets you specify the file transfer program (almost always IND$FILE) located on your host. You may also specify the location of a Translation table (from EBCDIC to ASCII). If the user has a translation table, it will be on their local drive. You must also specify the correct host Operating system before starting the transfer.

17. What LU types are available within TN3270?

• Any: Allows you to get the first available display session.
• Public: Allows you to get any type of available LU, within the Public Pool of LUs.
• Pooled: You need to have special rights (according to your host configuration) in order to get any available LU within a specific POOL. Therefore you need to define the POOL Name.
• Dedicated: Available LUs for dedicated users. Usually used when the user knows the LU name.

18. Can I change the Title name of the TN3270 Window?
Yes. Use the option Connect -> More -> Title, deselect the ‘Use Default’ option, and write down the desired new Title.

19. Can I reconnect automatically to the host when the session is disconnected?
Yes. Select the option Connect -> More -> Autoreconnect. Autoreconnect will reconnect you to your host's login screen immediately upon disconnection.

20. How do I connect to a TN3270E server?
You need to use the TN3270 Connection type, select the More button, and select the option "Use TN3270E Protocol’. It is recommended to define the Device Name if you already know it. If no Device Name is defined, you will be prompted to any first available session (be careful: you may get a printer session instead of a display session).

21. Does TN3270 support IBM3179G and IBM3192G terminal emulation?
Yes. The Graphics Enable option should be selected (Connect -> More). This option lets you show graphs on you session display.

22. Which types of SNA gateways can I connect with Chameleon 3270 Terminal?
You can connect to your host through two types of SNA gateways:

Microsoft SNA server -> select the NTServer tab

Novell Netware of SAA server -> select the NW4SAA tab

23. How can I create a new connection profile?
Fill in a description for this connection.

1. Fill in the appropriate fields the necessary information provided by the system administrator, to make a connection according to the connection method you want to use.
2. Press the Add button and your connection profile name will appear on the Connection Profile list.

24. How do you set a header for a session?
Go to Connect, click on the More button, Disable the "Use Default" check box and write the title you want. This is the name that appears in the title bar of the terminal emulation window when you are connected to the specified terminal emulation session.

25. How to keep the font to a fixed size (whether in full screen mode or otherwise)?
In order to be NOT in full screen mode, go to "Setting->fonts" option and deselect the "Adjust font to window" option. That will give you the possibility to resize the windows without changing the font size. You can not resize the window in TN3270 to more then the window should allow with the selected type and size of font. The TN3270 is " Form" based application, so you can see the maximum size arrived from the host.

26. Can I use the TN3270 as a NT service?
TN3270 cannot be used as a service of an NT. TN3270 application is a Telnet 3270 client, and you would need a Telnet Server application in order to allow it to be a service.

27. Can the TN3270 work without interaction with the desktop?
The only possibility you have is by using our HLLAPI interface. It does allow you to connect and receive data stream without interaction of any icons on your desktop.

28. What parameters are mandatory in the SAA configuration file?

• Server name
• Service name
• LU Name Type
• Device type
• LU/Pool name
• Model

29. What font is recommended to use in TN3270?
The NEWT font is recommended. You can use the adjust font to window option which automatically selects the most appropriate font when you resize the 3270 Terminal Emulator window.

30. What product enhancements have been made to TN3270 since v5.0?

Here is a list of product enhancements made to TN3270:

*Cham 4.5: Runs scripts that have been created using the Cham 4.5 or Simplified Script Type.

*Debug Mode. Choosing Debug from the Script menu starts the script editor in debug mode, making it possible to run and debug line by line.

32. What new terminal applications are included with v6.0?

The WinHLL Automation Server

This is an OLE automation object that automates the standard Windows HLLAPI functions (compatible with IBM EHLLAPI), as they relate to the TN3250 and TN5250 terminal emulators.

32. Tips:

• When looking for the "login prompt" do not include in it the sign : ‘>’. It is not recognized correctly and will not allow the Auto-login process to continue correctly.
• You can create an ICON from a connection profile very easily just by clicking the Icon button.
• You can create an ICON/Shortcut to launch the Emulator to connect directly to a certain host by adding the name of the connection profile on it’s command line, adding to it the configuration file name:

F:\NETMANAG.95\TN3270.EXE -FF:\NETMANAG.95\TN3270.CFG -C"connection to USA"

• If you don’t know what does a certain field stands for, the help button in this screen will give you all the information you may need.
