There are a number of system tuning parameters which you can manually insert in the ITERM.INI file in the Windows directory. These parameters allow certain default characteristics to be modified.

System Wide Changes

System wide changes can be made by adding or changing an entry in the [System.Settings] section of the ITERM.INI file. The parameters that can be changed are listed below:

Display Host Address

This entry allows you to disable the display of the IP host address or gateway in the Operator Information Area of the screen. The default is On. For example:


Display Host address = Off

Attn Format

This entry allows you to change the sequence used to send the SNA Attention signal to the host system. IBM’s PC/3270 uses a different format than other companies. If you want to use the IBM format,then use the following switch:


Attn Format = 1

Printer Font

This entry allows you to change the default printer font used to print the keyboard template from Times New Roman to any True Type font of your choice. For example:


Printer Font = Arial

Max Winsock Receive Size

This entry allows you to change the default receive size issued to the TCP/IP stack. By default, IntelliTerm uses a 20,000 byte block to receive data. You can lower this value to solve problems in low memory situations. For example:


Max Winsock Receive Size = 4096

Prompt on Close Windows

By default Distinct IntelliTerm will warn you if you try to close the application and a session is currently open. If you do not wish to be prompted before the program closes, enter the following line in the [System.Settings] section:


Prompt On Close = Off

Large Toolbar

By default, Distinct IntelliTerm uses fairly small icons which are easily readable up to 800x600 resolution. However, at 1024x768 and higher, the icons get somewhat small. To use the larger set of icons in the toolbar, add the following line to the [System.Settings] section:


Large Toolbar = On

You can also change the size of the buttons dynamically by right-clicking the toolbar and clicking the Large Icons checkbox. The toolbar is resized automatically as soon as you click OK.

Modify Tracing File

By default, the tracing file is created in the root of the current drive as ITERM.TRC. To change the location and name of the trace file, add the following line to the [System.Settings] section:



Allow NumLock Maps

By default, the plus and minus keys in the keypad area cannot be remapped when the NumLock key is toggled on. To allow these keys to be remapped even with the NumLock toggled on, add the following line to the [System.Settings] section:


Allow NumLock Maps=On

Type Ahead Timeout

By default, the Type Ahead will automatically timeout waiting for the host system to unlock the keyboard after 45 seconds. You can change this timeout by entering a new value in seconds using the following option in the [System.Settings] section:


Type Ahead Timeout=xx

Capture OIA

By default, the Operator Information Area (OIA) is also saved to the file when the Save Screen function is executed directly or via the dialog box. You can prevent the system from saving the OIA by adding the following line to the [System.Settings] section:


Capture OIA=Off

Display Field Info

By default, the system updates the Numeric Field and Operator Selectable Field indicators in the OIA every time the cursor is moved. If this causes too much overhead on your machine, (i.e. cursor movement appears slow), then disable it by adding the following line to the [System.Settings] section:


Display Field Info=Off

Maximum Sessions

By default, a user can allow up to twenty-six concurrent sessions with Distinct IntelliTerm. You can further the amount of sessions to a lower value by adding the Maximum Sessions line to the [System.Settings] section. Replace x with a value from 1 to 5 (inclusive).


Maximum Sessions=x

Host Language Support

You can change the host language after installation by changing the language name in the [System.Language] section. The valid language names are: USEnglish, UKEnglish, Swedish, AustrianGerman, CanadianFrench, and Norwegian.

For example:


Language = Swedish

ReRun Auto Quick-Key

By default, the Auto Quick-Key is executed when a session is initially created. It is also re-executed when the session is recreated using the “Auto Reconnect” feature. To prevent this from occurring, add the following line to the profile that you wish to disable the feature. For example, if the profile name is MVS, then search for the [MVS] section and add the ReRun Auto Quick-Key=Off line somewhere.

[...profile name...]

ReRun Auto Quick-Key = Off
