Using the Applets for Windows and Windows NT
Chapter 1	1 of 14

Using the Applets for Windows and Windows NT

Microsoft SNA Server includes Windows NT-based and Windows-based 3270 and 5250 Applets, which allow your personal computer (PC) to access IBM hosts or AS/400 [image] systems on the Systems Network Architecture (SNA) network. With the SNA Server 3270 Applet for Windows NT and Windows, you can access an IBM host using a single logical unit (LU) for your SNA session. An LU is a preset unit containing all the configuration information needed for a user or a program to establish a single interactive user session with another computer on the SNA network. With the SNA Server 5250 Applet for Windows NT and Windows, you can access an AS/400 system.

With the 3270 Applet, you can connect to the following host environments:

Virtual Machine/Conversational Monitor System (VM/CMS)

Time Sharing Option (TSO)

Customer Information Control System (CICS [image])

With the 5250 Applet, you can connect to an AS/400 environment.

With the 3270 Applet, you can transfer information between the host system and your computer without using an intermediate storage medium. This gives you the ability to:

Transfer a file back and forth between your computer and the host. You can then continue working with the file even if the host is unavailable or slow.

Edit a file and return it to the host where it can be shared by other users.

Print the information in the active window of a host application file.

Extract information from the host for further analysis on your computer.


Starting the Applet
Using the Applets for Windows and Windows NT	2 of 14

1.	In the Windows NT Program Manager, open the SNA Server program group.

2.	Activate the SNA Server 3270 Applet icon.

The 3270 Applet window appears.

To start the 5250 Applet

1.	In the Windows NT Program Manager, open the SNA Server program group.

2.	Activate the SNA Server 5250 Applet icon.

The 5250 Applet window appears.


Defining Session Settings
Using the Applets for Windows and Windows NT	3 of 14

Defining Session Settings

Before you can connect to a host (for the 3270 Applet) or AS/400 system (for the 5250 Applet), you must define the settings you will need for your session. To find out the correct session settings to use, contact your system administrator.


Session Settings for the 3270 Applet
Using the Applets for Windows and Windows NT	4 of 14

Session Settings for the 3270 Applet

With the 3270 Applet, you must define the session settings shown in the following list. To find out the correct session settings to use, contact your system administrator.

LU or Pool Name

LUs and LU pools are collections of configuration information that make it possible for your computer to connect to the host.

Host Code Page

The host code page specifies the EBCDIC code page translation tables used by the host. The default is United States.

To define session settings for the 3270 Applet

1.	From the Session menu, choose Session Configuration.

The 3270 Settings dialog box appears.

2.	In the LU or Pool Name box, select the correct LU or pool name.

Note

The list of LUs and LU Pools that appears is determined by SNA Server according to the network user name you used when logging on to the domain.

3.	In the Host Code Page box, select the correct host code page.

The default is United States.

4.	Choose the OK button.


Session Settings for the 5250 Applet
Using the Applets for Windows and Windows NT	5 of 14

Session Settings for the 5250 Applet

With the 5250 Applet, you can define the session settings shown in the following list. To find out the correct session settings to specify, contact your system administrator.

Local LU Alias

A local LU alias specifies a local LU. A local LU is a collection of configuration information that makes it possible for your computer to connect to the AS/400.

Note

If you leave Local LU Alias blank, SNA Server first checks the configuration for a Default Local APPC LU for the user or group logged on. If the Default Local APPC LU has been configured in SNA Server Admin, SNA Server uses that LU. If no such LU can be used, SNA Server attempts to assign an LU from the Default Outgoing Local APPC LU Pool. If no LUs are available from the Default Pool, the attempt to start the applet will fail. For more information on configuring default local LUs and LU pools, see the Microsoft SNA Server Administration Guide

Partner LU Alias

The Partner LU Alias is the same as the system name on the AS/400.

Note

If you leave Partner LU Alias blank, and a Default Remote APPC LU has been configured in SNA Server Admin for the user or group logged on, SNA Server uses that LU. For more information on configuring default remote LUs, see the  Microsoft SNA Server Administration Guide

Host Code Page

The host code page specifies the EBCDIC code page translation tables used by the host. The default is English-US.

Display Size

The display size specifies the size of the display on your screen.

With the 5250 Applet, you can also change the following default session setting, although this is generally not necessary.

Device Name

Normally, the AS/400 provides a default device name for your computer. If necessary, you can specify a different device name than the one provided by the AS/400.

For any 5250 emulator, SNA Server automatically generates a unique device name for each session, based on the local LU and a system-wide unique two-byte hexadecimal number. However, you can override this device name with another system-wide unique name.

To define basic session settings for the 5250 Applet

1.	From the Session menu, choose Session Configuration.

The 5250 Session Information dialog box appears.

2.	In the Local LU Alias box, type the Local LU Alias provided by your system administrator.

In some cases, the Local LU Alias provided by your system administrator may be the same as your user name. In other cases, your system administrator may instruct you to leave the box blank; this allows the SNA server to use the default local LU configured for your user name.

3.	In the Partner LU Alias box, select the system name of the AS/400, as provided by your system administrator.

Your system administrator may instruct you to leave the box blank; this allows the SNA server to use the default system name (also called the remote LU) configured for your user name.

4.	In the Host Code Page box, select the correct host code page.

The default is USA (English).

5.	Under Display Size, select the option button for the correct display size.

The default is 24 x 80.

6.	To specify a device name other than the default, in the Device Name box, type the correct device name.

Note

Device Name is described earlier in this section. Contact your system administrator to find out if you need to change the entry for Device Name.

7.	Choose the OK button.


Displaying of Pop-Up Messages in the 5250 Applet
Using the Applets for Windows and Windows NT	6 of 14

Displaying of Pop-Up Messages in the 5250 Applet

On clients running Windows version 3.x, you can control whether the 5250 Applet displays pop-up messages for every communication failure, or just for communication failures that occur during establishment of a session. You control this through lines in WIN.INI. (The pop-up message may contain information about the nature of a communication failure.)

To cause the 5250 Applet to display pop-up messages for every communication failure, including failures that occur after a session is established, add the following lines to the WIN.INI file on the client running Windows version 3.x:

[WIN5250]
APPC_ERRORS=1

To cause the 5250 Applet to display pop-up messages for communication failures only when the failures occur during establishment of a session, type the following lines into the WIN.INI file on the client running Windows version 3.x:

[WIN5250]
APPC_ERRORS=0

For this variable, the 5250 Applet defaults to 0, meaning that pop-up messages are displayed only for failures during establishment of a session.


Connecting to the Host Application
Using the Applets for Windows and Windows NT	7 of 14

Connecting to the Host Application

After defining session settings, you can use the 3270 or 5250 Applet to connect to the host or AS/400 application. Also, after defining session settings, you can automatically connect to the host or AS/400 application every time you start the 3270 or 5250 Applet.

To connect to the host or AS/400 application

From the Session menu, choose Connect.

A sign-on dialog box appears, ready for you to enter your user ID and password.

To disconnect from the host application

From the Session menu, choose Disconnect.

The host disconnects.

To turn on the Autoconnect option

From the Session menu, choose Autoconnect.

A checkmark indicates that Autoconnect is selected. When Autoconnect is selected and you start the applet, it automatically connects.

To turn off the Autoconnect option

From the Session menu, choose Autoconnect.

Autoconnect is no longer selected (no checkmark appears beside it).


Defining File Transfer Settings (3270 Emulation Only)
Using the Applets for Windows and Windows NT	8 of 14

Defining File Transfer Settings (3270 Emulation Only)

Using the 3270 Applet, you can transfer a file between your computer and a host application. However, before you can send a file to the host or receive a file from the host, you must define the transfer settings that you need. These settings tell the 3270 Applet which host environment you will be using — VM/CMS, TSO, or CICS — as well as the parameters for the connection between your computer and the host. Before starting this procedure, review the configuration parameters under step 3 to ensure that you have the necessary information at hand.

To define file transfer settings

1.	From the Transfer menu, choose Settings.

The File Transfer Settings dialog box appears.

2.	Under Host Operating System, select the option button for the correct host environment.

The host environment option that you select determines the rest of the settings you enter in the File Transfer Settings dialog box. Settings you do not need for your host environment are grayed and cannot be accessed.

3.	Find the items that apply to your configuration, and supply the information as follows:

Host Program Name

Specify the host program name by typing the host name for the program used by the 3270 Applet.

The default is IND$FILE.

Timeout

Specify the amount of time, in seconds, that the 3270 Applet will wait for a host response to the file transfer request.

The default is 30 seconds.

Packet Size

Specify the packet size transferred at one time. The larger the size, the faster the file is transferred.

A packet is a transmission unit of fixed maximum size, used as the basic unit on a packet-switching networks. A packet contains both a header and data, arranged in a specific format.

The maximum packet size is 32767; the default size is 8192.

Block Size (TSO)

Select the Block Size check box and specify the size of the blocks of data, in bytes, in the new data set on your TSO volume.

A data block is a string of data transmitted as a unit. A data set is a collection of data records among which there are logical relations.

The default block size is 80 bytes.

Issue Clear (VM/CMS and CICS)

Select this check box to request the host to clear the terminal screen before transferring files.

The default is selected (enabled) for CICS transfers and cleared (not enabled) for VM/CMS transfers.

Host Code Page

Select the correct EBCDIC code page translation table used by the host.

The default is United States 037.

PC Code Page

Select the correct ASCII code page translation table used by your computer.

The default is United States 437.

Record (VM/CMS and TSO)

Specify the type for the logical record length by selecting the correct option button for your configuration.

This parameter controls whether the logical record length — the number of characters in each record of a file transferred to the host — is fixed, variable, undefined, or default (that is, controlled by host defaults [TSO only]).

A transferred file that replaces or appends to an existing file automatically takes the logical record length of the existing file.

To update an existing host file, select Default.

To create a new host file, select the record length type: Fixed, Variable, or Undefined.

If you select Fixed, specify the logical record length in the Fixed box. The default is 80.

Space (TSO)

Select this check box to specify the space for a new data set, then select the option button that corresponds to the unit of measurement (Blocks, Tracks, or Cylinders) and type the number of units to allocate. To allocate additional space, in the second text box, type the number of additional blocks, tracks, or cylinders to allocate. To find out the correct amount of space to specify, contact your host administrator.

4.	Choose the OK button.


Specifying the File (3270 Emulation Only)
Using the Applets for Windows and Windows NT	9 of 14

Specifying the File (3270 Emulation Only)

Once you have defined the settings for transferring files, you can send a file to or receive a file from the host. You can select a file to transfer in one of two ways: by typing the name of the specific file to send or receive or by browsing through a list of available files.

To type the name of a specific file

1.	From the Transfer menu, choose Send File or Receive File.

A dialog box similar to that shown in Figure 1.1 or Figure 1.2 appears.

Figure 1.1    VM/CMS Send File Dialog Box

Figure 1.2    VM/CMS Receive File Dialog Box

2.	In the PC File Name box, type the path and name of the file to send or receive.

Caution

When receiving a file from the host application, if you type the name of an existing PC file, it will be overwritten by the host file.

3.	To review your settings, choose the Settings button; to continue, see the next section.

To browse through a list of available files

1.	From the Transfer menu, choose Send File or Receive File.

Either the Send File dialog box or the Receive File dialog box, similar to the ones shown in Figures 1.1 and 1.2, appears.

2.	Choose the Browse button.

The Open dialog box appears.

3.	In the File Name list, select the file you want to send or receive.

To see files of another type, select the type from the List Files Of Type box.

4.	Choose the OK button.

The Send File or Receive File dialog box reappears with your selection in the PC File Name box.

5.	To review your settings, choose the Settings button; to continue, see the next section.


Sending and Receiving a File (3270 Emulation Only)
Using the Applets for Windows and Windows NT	10 of 14

Sending and Receiving a File (3270 Emulation Only)

Once you have defined the settings you need to transfer files and selected the file to transfer, you can send a file to or receive a file from the host. To send or receive a file, you must supply certain configuration information. This information includes the host filename, host file type, host file mode, data set name, carriage return, whether you are appending to an existing file, EBCDIC conversion, and carriage return line feed. Before starting this procedure, review the configuration parameters under step 1 to ensure that you have the necessary information.

To send a file to or receive a file from the host

1.	After specifying the file, as described in the preceding section, find the items that apply to your configuration, and supply the information as follows:

Host File Name (VM/CMS and CICS)

Specify the host filename.

Host File Type (VM/CMS and CICS)

Specify the host file type.

For CICS, select either ASCII File or Binary File.

Host File Mode (VM/CMS)

Specify the host file mode, the specific minidisk where the user data resides. To find out the mode for a specific file, from an applet session, type the following command, substituting the name of the file for filename:

list filename * *

In the resulting display, the third column contains the file mode.

The default host file mode is A1.

Data Set Name (TSO)

Specify the host data set name. Be sure to include the Member name, in parentheses, if you are sending to or receiving from a host partitioned data set (PDS).

A PDS is a specific subset of the data in a set of files; the Member name is necessary to identify data within a PDS. The following is an example of a data set name for a PDS:

# SSAL01_CX_02560 Carriage Return (CICS)

Select the carriage return option for the file you are sending or receiving.

Delete CR/LF removes all carriage return/line feed characters from the file sent to the host. No CR/LF leaves the carriage return/line feed characters in the file when transferring to the host. None Of The Above uses the default implied by the type of file (ASCII or binary) being transferred.

The default for ASCII (being converted to EBCDIC) is CR/LF. The default for binary is No CR/LF, and CRLFs will not be interpreted.

Append To Existing File (send)

Select this check box to add new data to the end of an existing host file.

Convert To EBCDIC (send)

Select this check box to convert from ASCII to EBCDIC.

Convert From EBCDIC (receive)

Select this check box to convert from EBCDIC to ASCII. Use this option for text files rather than binary files.

Delete Carriage Return/Line Feed CR/LF (send)

Select this check box to replace all CR/LF characters with end-of-record marks.

Insert Carriage Return/Line Feed CR/LF (receive)

Select this check box to replace all end-of-record marks with CR/LF characters. Use this option for text files rather than binary files.

2.	Choose the OK button.

The 3270 Applet begins the file transfer.


Using Macros
Using the Applets for Windows and Windows NT	11 of 14

Using Macros

The 3270 and 5250 Applets provide macros for ease in using host function keys.

The macros for the 3270 Applet are as follows:

Macro	Description

Attention	Sends an Attention key to the host. The Attention key is used to temporarily stop the present display station activity.

Clear	Sends a Clear key to the host. This macro clears the display screen.

Reset 	Sends a Reset key to the host. Reset unlocks the keyboard and clears operator errors.

Sys Request	Sends a Sys Req key to the host. With most systems, use this macro to notify the host system that the display station is ready to select a new program or activity.

The macros for the 5250 Applet are as follows:

Macro	Description

Reset	Sends a Reset key to the host. Reset has the following functions:

   Causes the display station to leave insert mode.

   Cancels a diacritical-mark key and character key input.

   Ends the help and system request functions.

   Cancels a hexadecimal key.

   Clears operator errors.

   Unlocks the keyboard and removes the do-not-enter symbol displayed in the operating status line (except for the Security and Printer Not Ready keys).

Attention	Sends an Attention key to the host. The Attention key is used to temporarily stop the present display station activity and select a new activity.

Sys Request	Sends a Sys Req key to the host. Functions of Sys Req can vary depending on the host system. With most systems, use the macro to:

   Select and start an alternate job.

   Notify the host system that the display station is ready to select a new program or activity.

   Request that the keyboard be unlocked (after normal error-recovery action has failed) so that you can enter data.

Field Exit	Sends a Field Exit key to the host. Field Exit causes the cursor to exit an input field and null characters (displayed as blanks) are inserted from the current cursor location to the end of the field.

Field Plus	Sends a Field Plus key to the host. Field Plus causes the cursor to exit an input field and null characters (displayed as blanks) are inserted from the current cursor location to the end of the field. When entering numeric data, you can use this macro instead of the Field Exit macro.

Field Minus	Sends a Field Minus key to the host. Functions of Field Minus can vary with the system. On most systems, use this macro to operate the same way as the Field Plus and Field Exit functions, except that it is allowed only in signed-numeric and numeric-only fields. This macro inserts a minus sign in the last position of a signed numeric-only field, or it changes the last position of a numeric-only field to an alphabetic character. (The alphabetic character is used to tell the system the numeric value of the last position and that it is a negative field.)

Note that this macro can cause an error if it is used in any field not programmed to accept negative numbers as input.

To use a macro

From the Macro menu, select the correct macro.

The appropriate function key is sent to the host.

To do this, you select a portion of the displayed information and then copy it to the Microsoft Windows NT Clipboard. The Clipboard is a memory resource that stores the last information that was copied or cut. After copying information to the Clipboard, you can change to a different application and transfer the information into that application.

In reverse fashion, you can copy information from an application other than the applet, then paste the information into the applet. If the emulation session is in a state where information can be received (indicated by the status line), the pasted information will be entered as a series of keystrokes.

To copy and paste information displayed in the applet window

1.	Select the portion of the displayed information that you want to copy, or, from the Edit menu, choose Select All.

2.	From the Edit menu, choose Copy.

The selection is copied to the Clipboard.

3.	Change to the application in which you will insert the contents of the Clipboard.

4.	Position the cursor where you want to insert the contents of the Clipboard.

5.	From the Edit menu, choose Paste.

To copy information from an application and paste it into the applet window

1.	From the application, copy information to the Clipboard by using the application's standard copy command(s).

2.	Change to an active applet session, or start the applet and begin a session.

3.	Check to see that the session is in a state where keystrokes can be received.

4.	From the Edit menu, choose Paste.

The copied information is entered as a series of keystrokes.

Using the 3270 Applet for MS-DOS

This chapter tells how to use the 3270 Applet for MS-DOS. The introductory sections tell how to configure the applet; later sections tell how to start the applet, establish a session to the mainframe, and carry out file transfer.


Configuring the MS-DOS – Based Applet
Using the 3270 Applet for MS-DOS	2 of 11

Configuring the MS-DOS – Based Applet

At the MS-DOS prompt in the directory where you copied the files, type the following and then press ENTER:

3270cfg

The Configuration Utility menu is displayed on the screen. You use the Configuration Utility to configure the applet to run on your system and to customize your sessions to your preferences.


How to Get Around in the Configuration Utility
Using the 3270 Applet for MS-DOS	3 of 11

How to Get Around in the Configuration Utility

You can use either a mouse or a keyboard to make selections and work within the Configuration Utility. The following table explains how to use a mouse or a keyboard.

To	With the mouse	With the keyboard
Select a field	Point to the field and double-click the left button (this also opens the field's menu).	Use arrow keys or TAB key to move to a field and highlight it.

Go to (open) the menu for a particular field	Select the field.	Select the field, then press ENTER.
Exit a menu (return to the previous menu)	Click the right button.	Press ESC.
An example of a completed Configuration Utility menu is shown below.


The Environment Section
Using the 3270 Applet for MS-DOS	4 of 11

The Environment Section

This is the top section of the menu, containing the basic information the MS-DOS – based applet needs to connect to and communicate with the mainframe and display data on your computer screen.

Startup Name

The Startup Name field displays the filename used to define a particular configuration: 3270. Type this filename at the MS-DOS prompt to start the applet.

Connection

This field displays the type of connection the MS-DOS – based applet is using to communicate with the mainframe. The applet is using a connection to the Microsoft SNA Server.

LU Name

LU names identify LUs, the basic unit through which the MS-DOS – based applet establishes a session with a mainframe. Because LU names are defined at the gateway server, you must provide a name that exactly matches one defined at the gateway. Your system administrator can supply you with the appropriate LU name. It can be up to 10 characters long.

Keyboard

The MS-DOS – based applet supports several keyboard maps, as you'll see when you open the menu of available keyboards. The keyboard you choose depends on your keyboard's model (standard, enhanced, or 122-key) and the mapping you want to use.

When you select a keyboard, it tells the MS-DOS – based applet which keyboard map to use. The keyboard map assigns the locations that 3270 keys will have on your keyboard. Each 3270 key is assigned, or mapped, to a key on your keyboard. With this feature, you  can use a keyboard you're familiar with rather than learning new keystrokes for your workstation.

Display

Your display adapter determines the graphics capabilities of your PC and mainframe sessions. For information about your display type and its adapter, talk to your system administrator or check your display adapter manual.

Language

The default national language is English (U.S.). In addition, each language has a default MS-DOS code page and CECP mode options of Yes or No.


The Session Section
Using the 3270 Applet for MS-DOS	5 of 11

The Session Section

The Session section of the Main menu includes two kinds of sessions: PC and Host. A PC session interacts with PC applications. A Host session is a series of conversations and interactions that takes place between the mainframe and the display terminal. The sessions contain features and options that you can select and customize so that the MS-DOS – based applet meets your needs.

Status

PC Session

The Status feature can be set to one of three options: Concurrent, Non Concurrent, and Not Installed. Your selection here is determined by whether you want to allow PC applications to run while you're in a Host or a Notepad session, or whether you want PC applications to pause at such times.

Concurrent is the default. It allows a PC application to continue running while you're working in a Terminal or a Notepad session, or while the PC session is not in full-screen mode.

Non Concurrent suspends any PC activity while you're using a Terminal or a Notepad session. It also suspends PC activities while your computer is in windowed mode.

Not Installed means that the PC session isn't available.

Host Session

On at Startup is the default; selecting it automatically turns the session on when you load the MS-DOS – based applet.

Off at Startup prevents the session from automatically starting when you load the applet.

Name (not modifiable)

You'll see both a short name and a long name that identify each session.

Type (Host only)

The only available type of host session with this applet is a Terminal session. A Terminal session allows you to work in mainframe applications.

Size (Host only)

The MS-DOS – based applet supports several terminal model sizes. Terminal model sizes describe the ranges of horizontal rows by vertical columns displayed on your screen. Model 2 is the default with 24 rows x 80 columns; Model 3 is 32 x 80; Model 4 is 43 x 80; and Model 5 is 27 x 132.


The Startup Section
Using the 3270 Applet for MS-DOS	6 of 11

The Startup Section

The Startup section contains the features you can select to be present at startup, such as which session is active and information pertinent to file transfers.

Background FT

This feature controls the background file transfer available to you when you run the applet. Background file transfers have the advantage of letting you work in a PC session during file transfers. You can select a buffer size of 2K, 4K, or 8K for the transfer.

Multifreq 1

Selecting Yes turns on full-screen Model 5 (27 x 132) support using a multi-frequency type 1 monitor and an IBM VGA adapter. Type 1 includes the NEC [image] Multisync II and 3D monitor. Note that the MS-DOS – based applet automatically supports full-screen Model 5 monitors; you don't necessarily have to turn on this option for this support.

Warning

Make sure you know the type of monitor you're using before you set Multifreq 1 or Multifreq 2 to Yes. An incorrect setting may damage your monitor.

Multifreq 2

Selecting Yes turns on full-screen Model 5 (27 x 132) support using a multi-frequency type 2 monitor and an IBM VGA adapter. Type 2 includes the Mitsubishi [image] 1381A Diamond Scan monitor. Note that the MS-DOS – based applet automatically supports full-screen Model 5 monitors; you don't necessarily have to turn on this option for this support.

Mouse Support

Selecting Yes enables mouse support in the MS-DOS – based applet. This setting takes effect after you save your configuration and restart the applet. The default is No.

EMS Memory

Selecting Yes causes the MS-DOS – based applet to be loaded in expanded memory. This setting takes effect after you save your configuration and restart the applet. The default is No.


Saving the Configuration
Using the 3270 Applet for MS-DOS	7 of 11

Saving the Configuration

After you have performed the basic configuration procedure, you need to save the configuration.

To save the configuration

1.	Press F10. This brings up the Save menu with the Save & Exit field highlighted.

2.	Press ENTER to save your configuration.


Using the 3270 Applet for MS-DOS
Using the 3270 Applet for MS-DOS	8 of 11

Using the 3270 Applet for MS-DOS

The following procedures tell how to start the 3270 applet, display a session, turn host sessions off and on, and quit the applet.

To start the 3270 Applet for MS-DOS

1.	Change to the directory where the MS-DOS – based applet files are stored.

2.	At the MS-DOS prompt, type the following command, and then press ENTER:

3270

Now that the MS-DOS – based applet is running, you're ready to use it. Although the prompt looks like a regular MS-DOS prompt, you are now running a PC session inside the applet.

The following procedures tell the key combinations used for performing basic actions in the 3270 Applet for MS-DOS.

To display a 3270 session

Press CTRL+ALT+SPACEBAR.

If you're working in a busy mainframe environment, you might want to turn a session off to save system resources. Turning a session off allows you to end a mainframe session without unloading the MS-DOS – based applet.

If the applet was configured with the host session set to Off at Startup on your computer, you will need to turn a session on. (The default setting is On at Startup.)

To turn a session on or off

Press CTRL+ALT+O.

If you turn a session off, "Terminal Off" appears at the bottom of that session's screen. If you turn a session on, you can specify a different LU name for the session.

When you're ready to quit using the applet, you can exit and return to the MS-DOS prompt.

To quit the MS-DOS – based applet

1.	Press CTRL+ALT+K. A prompt appears at the bottom of your screen, saying

Quit Terminal Emulation (Y/N)?.

2.	Type y.

You should now be at your computer's MS-DOS prompt, in the directory containing the applet files.


Transferring Files
Using the 3270 Applet for MS-DOS	9 of 11

Transferring Files

Before starting a background file transfer, it is recommended that you use commands on the host to prevent host broadcast messages from being received by your emulator. This keeps the messages from interrupting the file transfer. After finishing the file transfer, use commands on the host to once again allow broadcast messages to reach your emulator.

File transfer involves two basic steps: using the File transfer menu to set parameters for the transfer, and starting the transfer by pressing CTRL+ENTER.


The File Transfer Menu
Using the 3270 Applet for MS-DOS	10 of 11

The File Transfer Menu

To bring up the File Transfer menu, press CTRL+ALT+F, T. An example of a completed menu is shown below.

The top line of the menu contains status information. The central portion consists of five fields that you set to define a transfer. The lower portion gives information for the currently selected field. You can correct or update a particular field by pressing TAB or ENTER to advance to that field and then retyping the information.

To send a file using background transfer

1.	Bring up the File Transfer menu by pressing CTRL+ALT+F, T.

If your machine beeps, you have not loaded background file transfer. Unload the MS-DOS – based applet and configure for background file transfer, as described in The Startup Section earlier in this chapter.

2.	In the Command field, type the appropriate Send command for your system, and press ENTER.

3.	In the PC file field, type the name of the existing PC file that you want to send to the mainframe, and then press ENTER. You can provide the full name of the file, including path and extension. Here's an example:

c:\mydir\myfile.txt

4.	In the Host File field, type the name that you want to give the file on the mainframe, and then press ENTER.

5.	Type the transfer options you need in the Options field, and then press ENTER.

Available options are listed under TRANSFER OPTIONS.

Note

The total number of characters used to complete the menu, including options, cannot exceed 128.

6.	Once you have completed the menu, start the transfer by pressing CTRL+ENTER.

To receive a file from the mainframe using background transfer

1.	Bring up the File Transfer menu by pressing CTRL+ALT+F, T.

2.	In the Command field, type the appropriate Receive command for your system, and then press ENTER.

3.	In the PC file field, type the name that you want given to the file when it is copied to your computer, and then press ENTER. You can provide the full name of the file, including path and extension. Here's an example:

c:\mydir\myfile.txt

4.	In the Host File field, type the name of the file you want to transfer to your computer, and then press ENTER.

5.	Type the transfer options you need in the Options field, and then press ENTER.

Available options are listed under TRANSFER OPTIONS.

Note

The total number of characters used to complete the menu, including options, cannot exceed 128.

6.	Once you have completed the menu, start the transfer by pressing CTRL+ENTER.


During the Transfer
Using the 3270 Applet for MS-DOS	11 of 11

During the Transfer

Once you have begun the transfer, you can jump to the PC session or any Terminal session other than the one performing the transfer and continue working.

Caution

Typing in the Terminal session that is performing the transfer may interfere with communications.

You can check on the status of the transfer at any time.

To check on the status of a file transfer or initiate the canceling of a file transfer

Press CTRL+ALT+F, T.

Pressing CTRL+ALT+F, T brings up the File Transfer menu again. The top line of the menu displays information about the number of characters transferred and the status of the transfer, as shown in the following table:

Time when information appears	Characters transferred	Status
Before the transfer	0	IDLE
During the transfer	Number of characters transferred so far	IN PROGRESS
After the transfer	Total number of characters transferred	COMPLETE
If there's an error	Number of characters transferred before the error occurred	ABENDED (with an error message)
When you bring up the File Transfer menu, it will ask you whether or not you want to cancel the transfer. To cancel the transfer, type y. To exit the menu without canceling, type n.

After the file transfer is finished, you can transfer another file. The fields on the screen will still reflect the previous transfer, so you only need to update those fields that change. Often, you only will need to update the PC file and Host File fields. To change a field, use the TAB key to select it, type the new information, and then press ENTER.

Appendix	4 of 5

Operator Information Area (OIA) Indicators For 3270

The OIA is used to display the status of a 3270 screen session. The OIA is the last (bottom) line displayed in the terminal window of the 3270 session. Except for the initial three positions (system connection indicators), status line indicators only appear when they apply.

The following tables describe the OIA and explain each indicator. In the table, position refers to the column(s) that a specific indicator occupies on the OIA, where the left-most column of the OIA is position 1. In addition, the "female" symbol used for certain system connection and input inhibited indicators cannot be displayed in this table. In its place is the "^" symbol.
