1. Introduction
This chapter presents PowerTerm LTC and its main features. It also describes the
basic steps on how to use PowerTerm LTC for users who are familiar with accessing
remote terminals.
This chapter includes the following topics:
• What is PowerTerm LTC?
• PowerTerm LTC Features
• System Requirements
• Getting Started
1.1. What is PowerTerm LTC?
PowerTerm LTC is a fully functional emulator for Linux Thin Clients operating
systems. It emulates various terminal types, including IBM, UNIX, HP, VMS and
Tandem. PowerTerm LTC enables you to connect to a single or to multiple hosts via
both network and remote connections.
PowerTerm LTC has two main features to enable the LTC to act and feel like a real
host terminal:
•Terminal display emulation, PowerTerm LTC emulates the exact display of
the chosen terminal. It presents host applications precisely as they would
appear on the terminal. Once the LTC connects to a host computer, all host
operations can be performed as if the LTC is an actual host terminal.
•Terminal keyboard emulation, PowerTerm LTC enables you to emulate the
selected terminal's keyboard by mapping the LTC keys to match the host
keys. Keyboard mapping definitions are stored in a .ptk file.
PowerTerm LTC also provides various options to customize and optimize the
working environment such as:
•Soft buttons, programmable buttons located at the bottom of the PowerTerm
LTC window.
•PowerTerm Script Language (PSL), a full-featured programming language,
which enables you to create scripts for automating tasks. For example, you
can create a PSL script for automatic login. Scripts can be used at startup of
PowerTerm LTC, or can be utilized any time during a PowerTerm LTC
session. PSL commands can also be assigned to the Soft buttons to enable
additional functions with a click of the mouse.
1.2. PowerTerm LTC Features

columns.
•Easy to use keyboard mapping
1.3. Getting Started
1.3.1. PowerTerm LTC Setup
To enable LTC-host interactions, you need to define two sets of parameters:
• Terminal parameters
• Communication parameters
All parameters are saved in a Terminal setup file where the default is called ptdef.*.
Setup file extensions are:
• pts for the Terminal setup file
• ptc for the Communication setup file
• ptk for the Keyboard definitions file
PowerTerm LTC provides the option to work with a single host or with multiple
hosts. You can create different setup configurations for working with each host to
enable each user a customized working environment. (For more information about
specifying and saving parameters, see chapters Defining Emulations and Defining
Connections.)
PowerTerm LTC

Users Guide
Working with a Single Terminal Connection
If you only need to connect to a single host connection, you should use the default
terminal setup and communication file. PowerTerm LTC automatically uses the
parameters in the setup file to start the system.
Working with Multiple Terminal Connections
If you are working with multiple terminal connections, you may need to use a
different setup file for each emulation. To create a setup file, you first need to
define the terminal setup and communication parameters, and then save these
parameters to a terminal setup file.
1.3.2. A Quick Guide through PowerTerm LTC
Step 1: Start PowerTerm LTC
Launch PowerTerm LTC.
When PowerTerm LTC is used for the first time, the PowerTerm LTC
window is automatically displayed together with the Connect dialog. After
the connection parameters have been defined, the Connect dialog will be
displayed according to your selected option.
PowerTerm LTC

Users Guide
PowerTerm LTC opens with the default terminal setup file. You can also open
PowerTerm LTC using a customized setup file, or script.
The most important feature of the PowerTerm LTC window is its work area, which
emulates a host terminal screen by displaying data entered on your terminal data
received from the host. (For more information on how to customize your desktop,
see chapter Manipulating the Desktop and Selecting Text)
Step 2: Select a Terminal Emulation
You can either select a terminal type for the current session or open a previously
defined terminal setup file.
To select terminal settings:
1. Select Terminal | Setup. The Terminal Setup dialog appears.
2. Select the Emulation tab.
3. Click one of the Terminal Types. The emulation type that you select changes
the number of setup tabs and, for IBM emulations, the PowerTerm LTC
windows display.
4. Define terminal settings by clicking the relevant Property page tab and
define setup parameters.
5. Click OK.
6. Save the settings by selecting File | Save Terminal Setup or Save Terminal
Setup As. The file is saved.
To open a previously defined Terminal setup file:
1. Select File | Open Terminal Setup. The Open File dialog appears.
2. Select your desired setup file and click OK.
Or,
1. Select Communication | Connect. The Connect dialog appears.
2. Type your desired setup file name in the Setup File field or alternatively click
the browse button and select the desired file in the Select File dialog.
Step 3: Connect to Host
After you have selected a terminal emulation, you need to define communication
parameters for the current session, or select a previously saved session from the
session list. PowerTerm LTC also provides an option to run a script file before you
connect to a host.
To connect to a host:
1. Select Communication | Connect. The Connect dialog appears.
2. Define communication parameters or select a session with previously defined
connection parameters from the Session list.
PowerTerm LTC

3. Click Connect. A connection is established to a host computer.
Step 4: Work with the Host
Once you have connected to a host, PowerTerm LTC enables you to work as if you
are working from a terminal.
PowerTerm LTC enables you to define print parameters, and print the terminal
screen or data transferred from the host application.
Step 5: Exit PowerTerm LTC
PowerTerm LTC provides different options when exiting PowerTerm LTC. You can
end a session automatically or be prompted with a confirmation message prior to
closing a session.
•Select File | Exit or press both <Alt> and <X> on the keyboard.
If you have changed terminal settings to Confirm Save in the Terminal Setup
dialog/Preference tab, PowerTerm LTC displays a warning message asking if
you want to update the terminal settings file. The message will point to the
name of the setup file currently loaded (ptdef.pts, if you use the default
settings). Click OK to update the terminal settings, or No to cancel the latest
changes and restore the default setup.

2.4. Hot Keys
Hot keys are keyboard shortcuts that you can use instead of selecting menu
commands. These hot keys refer to your standard LTC keyboard keys, before they
are mapped to terminal keys. Once hot keys are mapped, they lose their original
function and reflect the newly mapped terminal key. For example, if you map <Alt
F4> to the <Backspace> key on the terminal keyboard, it performs the function of
a <Backspace> key.
The following table lists the default PowerTerm LTC hot keys:
