A. Configuring the MS-DOS-based Applet
-----------------------------------------
The MS-DOS-based applet is provided with a default  
configuration that will allow it to run on most 
MS-DOS-based computers with VGA adapters.  The default
settings in the configuration are as follows:

LU Name:       Blank (which causes the applet to prompt
               for a name)
Keyboard:      CUSTOM KEYBOARD (that is, keyboard
               mapping like the 3270 Applet for Windows)
Display:       VGA
Language:      English (U.S.)
Host:          On at Startup
Background FT: Editor/Send/Recv 4K
Mouse Support: No              Multifreq 1: No
EMS Memory:    No              Multifreq 2: No


You can change the default settings by using the 
Configuration Utility.

> To start the Configuration Utility
------------------------------------
*  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.


A.1. 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.

------------------------------------------------------------


A.1.1. 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.

  ---------------------------------------------------------
  NOTE  If you have been assigned more than thirty 3270 
  LUs or LU pools at the gateway (the SNA server), only the
  first thirty will be accessible through the MS-DOS-based 
  applet.
  ---------------------------------------------------------

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, you tell 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.


A.1.2. 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.

Status: 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. 


A.1.3. 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 multifrequency type 1 monitor and an IBM 
  VGA adapter. Type 1 includes the NEC (R) 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 multifrequency type 2 monitor and an IBM 
  VGA adapter. Type 2 includes the Mitsubishi(R) 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.


A.2. 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.


B. 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.


C. Transferring Files with the 3270 Applet for MS-DOS
-----------------------------------------------------
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.


C.1. The File Transfer Menu
---------------------------
To bring up the File Transfer menu, press CTRL+ALT+F, T. 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."

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.  For 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. For 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.


C.2. 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     Characters
  appears         transferred     Status
  ----------------------------------------------------------
  Before the      0               IDLE

  If there's an   Number of       ABENDED (with
  error           characters      an error message)
		  transferred 
		  before the 
		  error occurred
--------------------------------------------------------------

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.


SECTION II
----------

D. Overview of the SNA Server Router 
------------------------------------
This section describes the SNA Server Router (Router), a 
replacement for the IBM AS/400 PC Support program router 
component. Router provides the software interface to an APPC 
network used by several popular 5250 emulators, including 
the 5250 emulator provided with IBM PC Support/400. This 
reduces the configuration required at the client. It also 
allows the client to communicate through an SNA server 
instead of directly with an AS/400, so that the client can 
use standard transports such as IPX/SPX, NetBEUI, or any 
other LAN or WAN transport. Without the SNA Server Router, 
the client must communicate directly with an AS/400 over 
DLC.

For information about PC Support, refer to your IBM PC 
Support manual(s).


D.1. Advantages of Router
-------------------------
Router provides the same interface as the PC Support program 
router component. It offers the following advantages:

* Unlike the PC Support program router component, Router 
  allows an MS-DOS-based client to use a single protocol 
  (such as NetBEUI). With PC Support, an MS-DOS-based 
  client must use the DLC protocol in addition to any other 
  protocol it uses.

* With Router, the DLC protocol does not need to be loaded.

------------------------------------------------------------
NOTE  Many 5250 emulators do not require the IBM PC Support 
router (or the SNA Server Router), but instead use the 
Windows APPC API. Examples of 5250 emulators that do not 
require the PC Support router are the SNA Server 5250 Applet 
and other 5250 emulators listed in the "SNA Server Companion 
Product Catalog."
------------------------------------------------------------


E. Installing Router
--------------------
Before you can use Router, you must take the following steps:

1. Install at least one SNA server.

2. Install the MS-DOS-based SNA Server client software on 
   the client that will use Router.

3. If the PC Support utilities (file transfer, shared 
   folders, IBM DOS 5250) are needed, install the IBM PC 
   Support program software on the client as well.


> To install Router
-------------------
1. Copy the ROUTER.EXE and INITRTR.EXE files to your PC 
   Support directory.

2. Comment out the line that loads the COMNDIS program in 
   your AUTOEXEC.BAT file. For example:

   rem c:\snaserv\rbin\comndis.com 2

   ---------------------------------------------------------
   NOTE  After the line that loads COMNDIS is commented 
   out, you must include the IRQ numbers of your network 
   adapter cards in the command line that starts Router. For 
   information, see "Starting Router."
   ---------------------------------------------------------

3. Comment out the following lines in your CONFIG.SYS file:

   rem device=<path>\DXMA0MOD.SYS
   rem device=<path>\DXM<x>0MOD.SYS

   where <path> is the path of the directory where these 
   drivers are located, and <x> can be either c for Token 
   Ring or e for Ethernet.

Since Router only replaces the router component of the 
PC Support program, you must always load the EIMPCS.SYS 
driver in your CONFIG.SYS file, along with any other driver 
options you need. For example, if you want to use shared 
folders, you may also need to load the ECYDDX.SYS driver. 
The following is an example of a CONFIG.SYS file for an 
MS-DOS-based SNA Server client:

DEVICE=C:\PCS\EIMPCS.SYS
DEVICE=C:\PCS\ECYDDX.SYS
DEVICE=C:\DOS\SETVER.EXE
DEVICE=C:\WINDOWS\HIMEM.SYS
DEVICE=C:\WINDOWS\EMM386.EXE  NoEMS  X=D800-DFFF
DOS=HIGH,UMB
FILES=3.0
SHELL=C:\DOS\COMMAND.COM C:\DOS\  /p
LASTDRIVE=Z
STACKS=9,256
DEVICE=C:\LANMAN.DOS\DRIVERS\PROTMAN\PROTMAN.DOS /i:C:\LANMAN.DOS
DEVICE=C:\LANMAN.DOS\DRIVERS\ETHERNET\UB\UBNEI.DOS

The following list describes the drivers that are loaded 
with PC Support and their function. Use the RMVPCS command 
to remove any drivers that you do not need.

Driver          Purpose
----------------------------------
EIMPCS.SYS      Memory management
ECYDDX.SYS      Shared folders


F. Starting Router
------------------
To start Router, you must first start the SnaBase
service and then use the ROUTER command with appropriate
options. This section shows the syntax to use with the
ROUTER command, and then gives a detailed procedure for 
starting Router.

The ROUTER command uses the following syntax:

ROUTER [/C<configpath>] [/BUFS=<buffer_count>] [/IRQ=<irq#>,<irq#>
OR
ROUTER [/D]

where

/C<configpath>
  Specifies the PC Support configuration file path. For 
  example, to indicate that your configuration file path is 
  C:\PCS\CONFIG.AS4, you would type:

ROUTER /CC:\PCS\CONFIG.AS4

The default path is CONFIG.PCS.

/BUFS=<buffer_count>
  Specifies the number of communication buffers Router 
  allocates. For <buffer_count>, specify an integer from 24 
  through 64.

  Each buffer takes approximately 280 bytes of memory. With 
  MS-DOS version 5.0 or later, Router allocates the memory 
  for communication buffers from upper memory if there are 
  enough free upper memory blocks available. Increase the 
  number of buffers to at least 48 if you transfer or copy 
  files (with the shared folders program).

  The default for <buffer_count> is 24.

/IRQ=<irq#>,<irq#>
  Specifies the IRQ numbers (in decimal) of your network 
  adapter cards. Separate multiple IRQ numbers with commas. 
  You must specify this option if you remove (or comment 
  out) the COMNDIS line from your AUTOEXEC.BAT file.

/D
  Removes the Router.

Use the following procedure to start Router with the ROUTER 
command.

> To start SNA Router
---------------------
1. On the MS-DOS-based SNA Server client, start the 
   SnaBase by typing:

   SNABASE

2. Change to your PC Support directory. For example, type:

   CD \PCS

3. Start Router by typing:

   ROUTER [<options>]

   where <options> are as described in the preceding 
   section.

4. Start the other PC Support components that you need, or 
   start the Windows environment and use Windows-based 5250-
   emulation programs, such as RUMBA/400.

   ---------------------------------------------------------   
   NOTE  If you are running Windows version 3.x, the SnaBase
   and SNA Server Router should be started before Windows 
   version 3.x is started.
   ---------------------------------------------------------


G. Modifying the Router Configuration File
------------------------------------------
Router is configured through the PC Support configuration 
file. You can use the default filename for this file, 
CONFIG.PCS, or you can rename your configuration file and 
specify the new path name in the /C option of the ROUTER
command, as described in the previous section.

The following CONFIG.PCS identifiers are used by Router. 
RTLN and TRLI are required, and the rest of the identifiers 
are optional:

INTL
  Specifies the interrupt number used by the PC Support 
  program components when they communicate with Router. 
  Specify a hexadecimal number from 60 through 68. This 
  identifier is optional. If you do not specify this 
  identifier, 68 is used. If you use extended memory 
  manager, do not use interrupt 67.

RTCU
  Specifies the ID to be used if a user ID is not specified 
  for the system on the TRLI identifier. This identifier is 
  optional. If you do not specify this identifier, you are 
  prompted for the user ID and password.

RTDN
  Provides the name of the AS/400 system used to start the 
  conversation if a name is not specified. This system name 
  must be one of the remote LU names in the SNA Server 
  configuration. This identifier is optional. If you do not 
  specify this identifier, the default is the first system 
  specified with TRLI.

RTLN
  Provides the name that uniquely identifies this computer 
  in the APPN network. This identifier is required. It is a 
  17-character name that must be the same as the fully
  qualified LU name of your local LU in the SNA server 
  configuration. For example:

  rtln appn.user1

  The name must contain the period between the two parts of 
  the fully qualified network name.

RTYP
  Specifies the router type. This identifier is optional. 
  If specified, RTYP must have a value of ITRN (local area 
  network). The ITRN is an IBM-defined value for the RTYP.

TRLI
  Specifies the link identification identifier. This 
  identifier is required. More than one identifier can be 
  specified for each AS/400 you communicate with. The 
  following example shows the full syntax of the TRLI 
  identifier:

  trli <system name for link>,<system address>,DSAP,  
  <user id>, MAXOUT, MAXIN, TIMERT1,TIMERT2,TIMERTI

  where <system name for link> is the name of the remote LU 
  (AS/400 name) you connect to and <user id> is used to 
  sign on to an AS/400.  The <system address> is required, 
  but this value is ignored by the SNA Server Router. 
  The <system address> may be specified as 000000000000.

  The <user id> is optional. If this parameter is not 
  specified, Router uses the common user ID or prompts 
  for a user ID.


H. Using Default LUs Specified in the PC Support Configuration
--------------------------------------------------------------
On a client running MS-DOS or Windows version 3.x, if you 
want to use the default LUs specified in the PC Support 
configuration file, you must set a variable in the SNA.INI 
file (for MS-DOS) or the WIN.INI file (for Windows version 
3.x):

OverrideDefaultLU=YES

When this variable is set to YES, SNA Server will use the 
default APPC LUs configured for PC Support; these LUs are 
specified on the RTLN line of the CONFIG.PCS file. 
Otherwise, SNA Server will use the default APPC LUs 
configured in SNA Server; these LUs are assigned to users 
or groups through SNA Server Admin or through the SNA 
Server command-line interface (snacfg).


I. Removing Router
------------------
After you install Router, you can remove it any time; 
however, you must first unload other PC Support components 
(workstation function, shared folders, and so on) by using 
the RMVPCS command.

To remove Router, type

   ROUTER /D

For additional information about PC Support functions, refer 
to your IBM PC support manual(s).

J. Working with Client Access/400
-----------------------------------
Client Access/400 (CA/400) is a new software product (in
beta as of August 1994) from IBM.  CA/400 adds a Windows 
interface to existing PC Support functionality.  CA/400 
can be used with Microsoft SNA Server version 2.1, 
specifically, with the MS-DOS-based client software and 
the SNA Server Router (Router).  Please note the following 
guidelines when using CA/400:

* If you plan to use CA/400 with Router, be sure to 
  read the information about Router in this README file
  or in Chapter 3 of the Microsoft SNA Server Installation Guide.

* When CA/400 is used with SNA Server software, the shared 
  folders component of CA/400 does not work.

* To run CA/400, you must start the underlying software
  components (for example, the client SnaBase software and 
  the Router) through MS-DOS, before starting the Windows 
  operating system.  The procedure is similar to the procedure
  for starting Router, as described in this README.

  > To start both Router and CA/400
  ---------------------------------
    1. On the client, make sure Windows is not started, so
       that only MS-DOS is running.
    2. At the MS-DOS prompt, start the SnaBase by typing
       SNABASE
    3. Change to the PC Support directory.  For example, type:
       CD \PCS
    4. Start SNA Server Router by typing
       ROUTER [<options>]
       where <options> are as described in this README.
    5. Start the other PC Support components that you need.
       If you want to use the extended version of PC Support,
       you must first start RTRMAP.EXE, to allow communication
       between the extended PC Support functions and Router.
       RTRMAP.EXE is provided with PC Support and can be found 
       on the I:\FL2 shared-folders directory on the AS/400.
    6. Start the PCSWIN component of PC Support by typing
       PCSWIN
    7. Start Windows.
    8. Start the CA/400 emulator software by double-clicking
       on the appropriate icon.
       When the emulator software starts for the first time,
       it displays the Customize Communications dialog box,
       which is also available through the Configure command
       in the Communications menu.
    9. In the Customize Communications dialog box, be sure
       that AS/400 PC Support Router is selected.
   10. Proceed with using the CA/400 software as described
       in the product documentation.
