Overview

Personal productivity tools

1783 Network Computing Terminal User’s Manual

Overview

The 1783 NCT is designed to address the requirements of host centric and network centric
users. The 1783 platform supports a real time operating system and a graphical user
interface (GUI). The presence of a micro-kernel, modularized POSIX compliant operating
system allows the 1783 to provide power and flexibility not available in server based
network terminals. The 1783 supports connectivity over Type A Coax, Ethernet, Twinax,
Token Ring, and Serial Ports to IBM hosts, UNIX hosts and Microsoft hosts in a windowing
environment. This connectivity allows a user simultaneous access to SNA, intranet and
Internet networks. Designed with no moving parts, the 1783 NCT is a zero maintenance
device that allows software installation and updates from a central location.

The 1783 NCT is easy to install, use, manage and support. Maintaining software and data
at a central location eliminates the need to store applications and/or data on a conventional
desktop workstation. Business applications, corporate intranets and the Internet can all
be accessed from one network terminal.

The 1783 NCT is unique among network computers because of its resident operating
system and the caching in flash memory of frequently used applications (such as the
1480 Emulator, Telnet, TN3270 and TN5250 host access, the Voyager
Citrix© ICA Client, and personal productivity tools). This flash memory caching effectively
eliminates the delay encountered with server-based systems when many users log on
simultaneously.

Inspecting the package

Before unpacking the 1783 NCT, inspect the carton for physical damage. If the exterior
package is damaged, contact your local sales office or distributor. Also contact the carrier
to request examination of the damage. The carrier is required to complete and sign a
damage report form. If the package is not damaged, remove the package contents which
includes a logic unit, a mouse, an AC power cable, and this user’s guide.

Setting up the 1783 NCT

To set up the 1783 NCT, refer to the diagram on the back of the logic unit and follow the
steps below:

CAUTION: The 1783 NCT has been designed to support the weight of 17-inch or smaller
display units. Display units larger than 17 inches MUST be placed beside the logic unit,
rather than on top.

1. Place the display unit on top (or beside) of the logic unit and position both within
connecting distance of an appropriate AC power outlet.

2. Make sure that the Power-On/Off switch is set to O (Off) on both the logic unit and
the display unit.

3. Place the keyboard in front of the logic unit. Pull out the feet underneath the keyboard
to adjust it to a higher setting, if desired. Insert the keyboard plug into the keyboard
connector on the back of the logic unit.

4. Refer to the owner’s manual that comes with your display unit for instructions on
how to attach the display unit’s data cable to the logic unit.

5. Plug the display unit’s AC power cable into an appropriate AC power outlet.

6. For the local screen print function, a printer connector is located on the back of the
logic unit. Attach the printer cable (provided with the printer) to the printer connector
on the back of the logic unit.

7. Insert the mouse’s cable connector into the mouse receptacle on the rear of the logic
unit. Check to ensure that the connector is firmly seated.

8. Plug one end of the power cable into the AC connector on the back of the logic unit.
Plug the other end of the AC power cable into the wall receptacle.

socket on the two-socket end of the T-connector cable.

2. Push the connector into the socket and turn the retaining ring clockwise until tight.

3. Align the 9-pin Sub-D connector end of the T-connector cable with the twinax
connector on the back of the logic element. Connect the cable to the logic element
and secure it in place by turning the retaining screws until tight.

4. If there are other terminals in the daisy chain, connect the second cable from the next
terminal to the unused socket of the two-socket end of the T-connector cable before
attaching the T-connector cable to the back of the logic element.

Chapter 3: Connecting the 1783 NCT

5. Make sure the twinax line is terminated properly. The last T-connector should have
one input open. If the last device is a Visara device, it must has a T-connector. If the
last device is not a Visara device, ensure that it is terminated correctly according to
the manufacturer’s instructions.

Note: When one connector of the two-socket end of twinax cable is unattached, the cable
is self-terminating. When the single end of the connector cable is unattached, the cable is
in Pass Through mode, and signals continue on to the next connected device. Never attach
the twinax cable directly to the logic element.

Powering up

After the 1783 NCT has been properly installed and connected, it is ready to operate
online. To ensure that the 1783 NCT is prepared for operating, perform the following
procedure. If you encounter operational difficulty or if the unit malfunctions, contact
your system administrator.

1. Set the Power-On/Off switch to On ( | ) to turn on power.

2. If the Power-On indicator does not light, check the power and make sure the unit is
completely plugged in. If the mouse pointer does not appear, or the Taskbar does not
appear, check to see if connecting cables are securely connected to the back of the
logic unit.

3. A beep indicates that the terminal is connected properly. If you hear more than one
beep, check the table on the following page for actions to take.

Using the 1783 NCT

This section introduces the new operating environment of the 1783 Network Computing
Terminal (NCT). It explains how to do most tasks and provides tips for getting the most
out of the NCT.

If you have used windowing systems before, the “look and feel” will seem quite natural.
If not, the intuitive interface is easy to learn and use.

What should I do first?

First, read through the next section - all the basics about using the mouse and working
with windows are explained, and some handy keyboard shortcuts are included. After
reading this section, familiarize yourself with the display’s workspace. Try starting an
application from the start menu - the Day Minder is a good place to start.

How to start the 1783

The system has been set up to start automatically at power-up. Your user ID and/or password
may be required in the 1783 NCT login dialog box.

A typical workspace

After the 1783 has started, it will display a workspace, an area in which you can run
applications and display windows. Here is a typical workspace, with some sample
applications:

At the very
bottom of the
screen, the
Taskbar shows
at a glance all
the applications
available on
your desktop.
The taskbar
allows quick
switching from
one application
to another. To
learn how to use
the Taskbar, see

Using the
Taskbar in this

section.

707042-0024-2

Using the mouse

Two common mouse operations are:

• Clicking – Pressing and releasing a mouse button.

• Dragging – Holding down a mouse button, moving the mouse, and then releasing the

button.

Note: When the word “click” or “drag” is used in this documentation, and no mouse
button is specified, use the LEFT mouse button. When the right button should be used
you will be explicitly instructed to do so.

Use the right mouse button to bring up a context-sensitive menu in most applications.

Pointers

As the mouse is moved, the pointer sometimes changes to provide feedback. Here are the
pointers most often seen:

Chapter 4: Using Windows

Basic pointer - point to objects to be selected
or to indicate where the cursor should be
positioned.

Busy pointer - Indicates that an operation is
in process and must finish before data entry
can be resumed.

Resize pointer - appears when the pointer
passes over a window frame; the two arrows
indicate the direction the window can be
resized.

Move pointer - appears when the pointer
passes over a window title bar; simply hold
down the mouse button and drag the window
to a new location.

I-beam pointer - appears in text-entry fields
to indicate that the application is ready to
accept keyboard input.

No-input pointer - Indicates the window is
not accepting input.

Application help

Most windows include these elements:

• Window menu button – Provides modification tools for the window (Restore, Move,

Size, Minimize, Maximize, To Back and Close).

• Minimize button – Reduce the window to an application button in the Taskbar. To

bring the window back up, click the application button on the Taskbar.

• Maximize/Restore button – Expand the window to fill the current workspace, or

restore it to its previous size after maximizing.

• Title bar – Displays the name of the application. The title bar is also where the mouse

pointer should be positioned in order to move the window.

• Frame – Changes color to indicate the focus window (that is, the one that’s ready for

input) on the workspace. The frame is also the area to grab to resize the window.

• Resize corner – Allows shrinking or stretching of the window.

• Close button – Some applications may use this convenient method of closing the

window.

707042-0024-4

Using the Window Menu

To open an application’s Window menu, click on the Window menu button in the window’s
upper left corner.

The Window menu allows you to:

• Restore the window’s size (after maximizing or minimizing it).

• Move the window – the window will track the mouse pointer until the mouse button

is clicked.

• Size the window – as the pointer is moved outside the frame, an outline will track it

until the mouse button is clicked.

• Minimize the window – reduces the window to an application button in the Taskbar.

To bring the window back up, just click on the button in the Taskbar.

• Maximize the window – expands the window to fill the current workspace.

• To Back – pushes the window behind any other windows that are open on the

workspace.

• Close – closes the application. An application can also be closed by double-clicking

on the menu button.

Chapter 4: Using Windows

CAUTION: Selecting the Close item may immediately terminate the application running
in that window without prompting you to confirm. Always remember to save your work
before you click on Close!

Note: Some tabs or tool bar icons may be subdued or “grayed out”; these tasks are not
accessible at this time.

Using the Taskbar

The Taskbar provides a quick and easy way to switch from one application to another and
to restore applications to their normal size on the workspace.

The Taskbar includes the following:

• Application list button -

your use by your system administrator.

• A label button for each application that is running. The label will appear whether the

application is visible on the screen or in the minimized mode.

To start-up an available application:

1. Click the

2. Select the application you wish to work with.

displays a menu of applications made available for

button. The menu of applications will appear.

To switch to any running application, click on the application’s button on the Taskbar.
The application’s window will be restored if minimized, brought to the front, and will
become the focus window.

Note: The system administrator may have configured your 1783 NCT to automatically
start an application in full screen mode when the 1783 NCT is powered on. The application’s
section in this document will describe how to access the taskbar from a full screen.

LPR (Line Print Remote)/LPD (Line Print Daemon) is a print server protocol widely
used on the internet for communicating between clients and servers. An LPR-enabled
device (the 1783, for instance) requests a LPD-enabled device (usually a printer or
print server) to print a specific print job. The 1783 can act as an LPR-enabled device
and/or an LPD-enabled device. Following are descriptions of how to configure the 1783
for LPR/LPD.

Remote Printing must be configured to enable LPR printing for the following 1783
applications:

• VT220 • 1480 Emulation

• TN3270E • 1490 Emulation

• TN5250 • Voyager Web Browser

The 1783 supports a total of nine remote printers. Three of these printers are static-defined
and cannot be deleted. The remaining six are user-defined. The three static-defined printers
are:

• lan_hp

• lan_ps

• lan_epson

Selecting data fields

The application program may be designed to present to you certain fields that can be
selected for further processing by the application program. These fields are marked
with a “?”.

To select a field, perform one of the following actions:

• Press the CrSel key

• Move the cursor to cover any character in the field or to cover the “?” and click the

right mouse button.

“ > ” replaces the “?” associated with the field you select. If you accidentally select the
wrong field, press the CrSel key or right mouse button to deselect it.

707042-002 6-5

1783 Network Computing Terminal User’s Manual

To send the field(s) to the application program for processing, do one of the following,
depending on how the application program was designed:

• Press the Enter key.

• Press the CrSel key after positioning the cursor on an attention field. (Attention

fields are marked with &’s and spaces.)

• Position the mouse cursor to point to the desired attention field and click the

right mouse button.

Sending data

To send the displayed data to the host application before continuing to enter data:

1. Check to be sure that all fields required by the application have been filled.

Note: When a data character is entered in the next-to-last character position on the screen,
the audible alarm sounds to remind you that the cursor is near the end of the screen. If
data entry continues, the cursor “wraps”’ and reappears in the first available character
position of the screen. Subsequently entered characters replace displayed characters,
resulting in loss of previous entries.

2. Press the Enter key to send the displayed data to the host application.

3. Press the Clear key. This has the following effect:

• Erases all displayed data on the screen

• Returns the cursor to the first available character position

• Signals the host application that a “clear” operation has occurred.

HAP Menu

The Host Addressable Print feature enables the host to send print requests to the 1783’s
attached printer. LU2 (screen) prints are always formatted by the display according to the
printer menu selections. To enable or disable HAP, click the HAP Menu button from
within the 1480 Print Setup Screen. The Host Addressable Print configuration screen will
appear:

• Enable HAP – Select to enable the HAP feature.

• Suppress Null Lines – Selection of this item will cause null lines to be removed

from formatted (40/64/80 CPI) HAP LU3 prints. Null lines are lines that contain only
non-printable characters (such as nulls, attributes or alphanumeric characters in a non­print field).

• Suppress automatic line feed when:

– CR at MPP + 1 – If this option is selected, when the printer reaches the

Maximum Print Position + 1 (the end of the print line), the carriage returns to the
beginning of the line without a line feed. The next printed characters will overwrite
the current line of printed characters. If this option is not selected, (the default),
when the printer reaches the end of the line, the carriage returns to the beginning
of the line and drops down one line.

– NL at MPP + 1 – If this option is selected, the printer does not execute a line

feed if there is a new line command at the Maximum Print Position + 1 (the end
of the print line). The printer begins printing on the next line. If this option is not
selected (the default), when the printer reaches the end of the line, it executes two
line feeds.

– FF at print end – If this option is selected, the printer does not execute a line

feed after a form feed. If this option is not selected (the default), the printer
executes a line feed after a form feed. Characters printed on the new page begin
on the second line.

6-16 707042-002

Chapter 6: 1480 CUT emulator

• FF ignored when not in first print position – If this option is selected, a form

feed character in the first position or next to the maximum print position is executed
while form feed commands in any other positions are printed as blank characters and
are otherwise ignored. If this option is not selected, all form feed commands are
executed.

• FF takes position if followed by data – If this option is selected, and if the form

feed character is not at the end of the print data, a form feed is executed and a blank
character is printed in the first position on the next page. Subsequent printing starts in
the second position on the new page. If this option is not selected, the form feed
character is not printed as a blank character and subsequent printing starts in the first
position on the new page.

• FF at end of print – If this option is selected, the printer ejects the last printed page

and subsequent printing begins on the new page. If this option is not selected, the last
page is not ejected and a line feed is executed. Subsequent printing begins on the new
line of the current page.

• Transparent Text Mode

– Coax – data included in an SCS Transparent Mode command (35H) is printed in

the LU1 environment as follows:

• Valid EBCDIC characters are translated and printed normally.

• Invalid EBCDIC characters (SNA character string [SCS] commands) are

printed as hyphens.

– ASCII – all data included in the command is sent through to the printer

untranslated. The following setup values are not sent to the printer during
initialization:

• Chars/Inch

• Lines/Inch

• Quality

• Printer Keys – Allow the operator to send either a PA1, PA2, or Cancel to the

application. The operator selects one of the functions (PA1, PA2, or Cancel) and
then clicks the SEND button. (Cancel is effective only in LU1 type print sessions.)

Click OK to save the changes and exit the screen, or Cancel to discard the changes
and exit.

Note: For changes to the HAP Menu to become effective, the 1480 must be restarted via
the Miscellaneous Menu, or by turning the unit off and back on again.

Dual Screen feature

The 1783 dual screen feature is provided by a special software program on the main logic
board. With the 1783 NCT Display Station in 1480 Emulation mode, you can display and
operate two sessions on one monitor in either a side-by-side format or a zoomed session
(that is, one of the two sessions occupies the entire display surface and you toggle between
the two sessions). Fields can also be copied from one session to the other. Dual screen
sessions are supported on a display configured as a Mod 2, 3, or 4.

Configuration requirements

To support Dual Screen mode, the controller must be configured for two or more logical
sessions on the display terminal’s port. In addition, PC File Transfer mode must be set for
those ports that use the Mark/Paste function of the 1783.

The 1783 must be configured as follows to be able to exercise the enhanced dual
screen features:

• The NCT 1480 Emulator must be in either Mod 2, 3, or 4 mode with Partitioning

deselected. (See Chapter 6: Defining and Selecting Features.)

• Host Addressable Printing must be disabled.

• The 1783 must be configured for video mode of 1024 x 768. (See Chapter 11:

Configuring NCT Miscellaneous.)

Mark

To select a field as the source field for a subsequent paste operation, position the cursor
anywhere within the field and hold down the Alt key while pressing the F4 key (Mark).
See Mark/Paste below for a complete description.

Paste

To select a field as the target field and paste source data into that field, move the cursor to
the target field and hold the Alt key while pressing the F5 key (Paste). The data in the
source field is pasted into the target field. If there is already data in the target field, that
data is overwritten with the data from the source field. See Mark, above, for instructions
on how to select a source field. The target field cannot be in the same session as the
source field. See Mark/Paste below for additional information about mark and paste.

Mark/Paste

Use the Mark/Paste feature to copy data between sessions. With this feature, data can
quickly be marked and pasted between fields in different sessions.

Mark field

The mark field is the field highlighted as the source data field. The data to be pasted must
be within a displayed field. Data cannot be marked for pasting if it is in a nondisplayable
field. Data can be pasted from protected as well as unprotected fields. The mark field
must be selected before selecting the paste field.

To select the source or mark field, position the cursor anywhere within the field, then
press and hold down the Alt key while pressing the F4 key (Mark). The field is displayed
in reverse video to indicate it is selected. If the Mark key is pressed while a field is
already selected, the selected field is deselected. The field is also deselected after one of
the Paste keys is pressed or if the session with the selected field is reselected with the
Select Right or Select Left key. A session with a selected field is frozen and does not
receive coax updates.

After selecting a field as the source or mark field, use the Select Left or Select Right key
to make the opposite session the active session, then move the cursor to the target field.

Paste field

The paste field is the field that receives the data from the mark field and it cannot be in the
same session as the mark field. The field that receives the pasted data must be an
unprotected field. Standard data truncation rules apply when the paste and mark fields are
of different lengths. If the paste field is longer than the mark field, data is replaced in the
paste field only up to the length of the mark field. If the paste field is shorter than the
mark field, data is truncated up to the length of the paste field. The data that has been
pasted is temporary until an Aid key (Enter or F key) is pressed; if a Select Right or Select
Left key is pressed before an Aid key, the pasted data is lost.

Communication Setup

Chapter 7: 1490 Twinax Emulator

Terminal Mode

Consult the system operator before changing this option.

The 1783 in 1490 mode can operate in two different terminal modes. By enabling up to
two independent host sessions to be configured, each with a different address on the
system, multiple host functions can be active simultaneously.

• One-Display – The 1490 operates as a single display station with one address. This

is the default setting. Local screen printing is available.

• One-Display-Printer – Both the display and attached printer are logically connected

to the host, each having a different address. In this mode, host addressable printing is
enabled.

Display Address

The display address is the display station’s logical address on the System/3X or AS/400
port. Ask the system supervisor for this address. The 1490 will not operate online until
you enter this address. No default address is set at the factory.

By selecting one of the 132-column monochrome emulations, you can enable a 1490
display station attached to a System/3X to have 132-column capability, even though the
System/3X does not support 132-column color displays.

The Display Emulation option is also useful when installing and configuring devices
where system support services are not readily available (for example, at a remote site).
You can select the emulation of the display that is already configured on your system
without having to change the host configuration.

In this Chapter...

Telnet Terminal

TN3270

TN5250

VT220

1783 Network Computing Terminal User’s Manual

Telnet Terminal

What is Telnet?

Telnet, using the Telnet protocol and the Internet, enables the user to gain access to
computer systems around the world.

In effect, the 1783 NCT functions as though it were a terminal connected to a remote
host. Once logged in, whatever tools are provided on the host can be used to do a variety
of things, such as:

• search databases to locate targeted information

• run specialized programs

• enter into online discussions

Telnet makes it possible for your terminal to “look like” whatever terminal the host
normally supports. An exception is certain IBM mainframe hosts running 3270
applications. To access a host as a 3270-type terminal, use the TN3270 feature, described
later in this section.

To gain permission to access a remote host, you can look up standard userids distributed
by those hosts whose administrators encourage public access, or you can set up an account
with a host and acquire a private userid and password. Some host administrators set up
access so that you can log in directly without a userid or password. Some provide special
port identifiers that need to be used.

In all cases, the host name of the computer system you wish to access is required.

Logging in to a remote host

To connect and log in to a remote host:

1. Click the button in the lower left hand corner of the screen. The application
menu will appear.

2. Click Telnet to start a Telnet session.

You will see this prompt in the window:

telnet >

Type :

open host

where host is the official name, an alias, or the Internet address of the
computer system to which you wish to connect. For example,

open {host}.{domain}.com

Note: If the host requires that a port number be specified when connecting, simply append
the port number to the host name, separated by a space.

707042-0028-2

Chapter 8: Using Telnet, TN3270, TN5250 and VT220

Telnet will connect to the remote host. The host then will normally respond with a welcome
and will lead you through its log in process. Log in, employing one of the following
combinations:

• With the userid and password supplied by the administrator of the host

• With just a userid (some hosts do not require passwords)

• Neither, if the remote host has been set up for it.

Once connected, use the menus, commands and features of the remote host, which are
largely text-based and can vary from host to host.

Logging out of a remote host

When you are finished using the remote host, use that host’s normal log out command.
Telnet will automatically finish running.

To disconnect from the host when its log out command is not available, or if you are stuck
for any other reason, enter one of the following:

• Ctrl - ]

• the escape character displayed by the host upon logging in.

Recommended reference guides

Telnet enables many special telecommunication features to be configured, such as how
carriage returns or interrupts are processed. Such features may be needed when accessing
a non-Unix remote host. Contact your system administrator or refer to one of the
following references:

TN3270

What is TN3270?

Like Telnet, TN3270 enables access to programs running on remote hosts. Unlike Telnet,
TN3270 provides the means to access 3270 programs running on IBM mainframes.

TN3270 enables the 1783 NCT to function as though it were a 3279 mod 2, mod 3, mod
4, or mod 5 terminal. Unlike Telnet, TN3270 can manipulate the entire screen image,
fields and function keys, in a way identical to a 3270 terminal. TN3270 provides the
following standard features:

• Window Menus – The window menus offer simplicity and ease of use for all setup

functions.

• Color Display – The color monitor is programmable in seven colors.

• Switchable Screen Formats – TN3270 supports four (4) screen sizes that can be

selected from setup menus. The server to which the TN3270 client attaches must be
configured to support the screen size used. Check with your system administrator.

• Mono/DualCase Mode – Allows characters to be displayed as all uppercase

characters or as upper- and lowercase characters.

• Mark Unprotected Field Indicator – The 1480 CUT Emulator can be requested

to mark unprotected fields with a special character.

• Row/Column Indicator – Displays the current cursor location on the operator

status row.

• Numeric Lock – Allows a field to be defined to accept only numeric characters and

the Period, Minus, and Dup keys. The comma may be substituted for the period on
some international keyboards.

• Multiple Sessions – A maximum of 10 sessions can be accessed with this emulator.

Copy/Paste Between TN3270 Sessions

Use the Copy/Paste feature to copy data between sessions or applications. This feature
allows you to quickly mark, copy and paste data between fields in different sessions.

The mark field is the area which is highlighted as the data source. The data to be pasted
must be within a displayed field. Data cannot be marked for pasting if it is in a
nondisplayable field. Data may be pasted from protected as well as unprotected fields.
You must select the mark field before you select the paste field.

Mark/Copy Field

To select the mark field, position the cursor with the mouse, then press and hold the Shift
key while dragging the cursor over the source field you wish to copy. The mark field is
displayed in reverse video to indicate that it has been selected. The choice between
“Standard” (default) and “Frame” in the Screen Setup, Edit Select Mode (as shown above),
will either highlight text lines or will select complete text blocks.

Note: Data can be marked and copied from protected as well as unprotected fields.

After selecting a field, press Alt C to copy selection into the clipboard where it may be
used to paste to other sessions.

Data may also be copied from other applications into a TN3270 session as long as the
applications support “text only” copy.

707042-0028-14

Chapter 8: Using Telnet, TN3270, TN5250 and VT220

Paste Field

The paste field is the field that receives the data from the mark field. The paste field must
be an unprotected field. Standard data truncation rules apply when the paste and mark
fields are of different lengths. If the paste field is longer than the mark field, data is
replaced in the paste field only up to the length of the mark field. If the paste field is
shorter than the mark field, data is truncated up to the length of the paste field. The data
that has been pasted is temporary until you press an Aid key (Enter or F key). To paste the
data you select using the Copy/Paste, position the cursor with the mouse and press Alt V.

Copy/Paste From Calculator to TN3270 Session

All entries on the calculator are automatically stored into the clipboard, therefore, there is
no need to copy the field. Perform the calculation you require, switch back to the session
and place the cursor where the data is required. Press Alt V to paste the calculated field.

Note: Every entry on the calculator overrides the buffer in the clipboard. Only the last
entry/calculation is available.

Recommended reference guide

Like Telnet, TN5250 enables the user to access programs running on remote hosts. TN5250
provides the means to access 5250 programs running on IBM midframes.

TN5250 can manipulate the entire screen image, fields and function keys, in a way identical
to a 5250 terminal. TN5250 provides the following standard features:

• Window Menus – The window menus offer simplicity and ease of use for all
setup functions.

• Color Display – The color monitor is programmable in seven colors.

• Row/Column Indicator – Displays the current cursor location on the operator

status row.

• Multiple Sessions – A maximum of 10 sessions can be accessed with this emulator.

Connecting to a TN5250 session

TN5250 will connect to the remote host. The host then will normally respond with a
welcome and will lead you through its log in process. Log in, employing one of the
following combinations:

• With the userid and password supplied by the administrator of the host

• With just a userid (some hosts do not require passwords)

• Neither, if the remote host has been set up for it.

To connect to a TN5250 remote host from the main TN5250 screen:

1. Click Session to open the TN5250 Session menu.

2. Click Connect.

Once connected, use the menus, commands and features of the remote host to access and
run 5250 applications.
