IBM OPERATING SYSTEM/2 EXTENDED EDITION VERSION 1.3
COMMUNICATIONS MANAGER
CORRECTIVE SERVICE DISKETTE
This version of the Communications Manager contains two new enhancements.
These enhancements are described within and are not included in the current
publications.

5250 Emulator in a text window...................................2
Batch Configuration Utility......................................4

5250 EMULATOR IN A TEXT WINDOW
This version of the Communications Manager 5250 emulator contains an
enhancement that enables the 5250 emulator to operate in a Presentation
Manager text window or as a full screen application. The functionality of
the emulator remains the same as in previous releases and this enhancement
adds the ability to display the 5250 presentation space in a text window.
By virtue of operating within a text window, standard window services and
options such as mark and copy are available to the user. Refer to the
on-line OS/2 windowed application help text for a description of these
services and options. The help can be accessed from the emulator window by
pressing the Shift-Esc key.
In addition to the standard text window functions, support is provided to
mimic some of the functions of the windowed 3270 emulator. These are:
o The emulator will save its size and position for subsequent start-ups
when the Save option is selected from the Desktop menu of the Desktop
Manager.
o Operator error conditions are cleared when cursor type keys are pressed.
o Cursor join (cursor is moved to the mouse pointer location when the mouse
button one is pressed).
o Beeping will occur on screen updates when the 5250 emulator does not have
focus and, if the window is minimized, the icon will change to reflect
the updated screen.
There are a few text window operational characteristics that also apply to
the 5250 emulator in a text window that are worth highlighting.
1. This version of the 5250 emulator is not a PM application and does not
have the same characteristics as the 3270 emulator which is a PM applica-
tion.
2. There may be only one 5250 text window and when there are multiple 5250
sessions active, a hotkey is used to move between sessions. This is the
same as the full screen operation.
3. The following keys are handled by the PM shell and are not available to
text windowed applications. These key combinations cannot be remapped
for the 5250 emulator when in the text window mode.
Ctl-C, Ctl-Q, Ctl-S, Ctl-P, Alt-Tab, S-Esc
4. The 5250 emulator does not perform an exit check on a cursor join opera-
tion. For example, an operator error will not be generated when a user
uses the mouse to move the cursor out of an unfilled Mandatory Fill type
of field.
5. With the system default font for text windows, you may find that the emu-
lator window does not fill the entire display screen when the window is
maximized. Selecting a different font size from the "Font Size..." option
of the emulator window's system menu will allow you to fill the screen
with the maximized emulator window.
6. Windowed text written with a color of blue, red, or pink may be difficult
to read depending on the type of monitor being used for display. If you
experience difficulty reading certain color text, you may want to change
the 5250 Work Station Features configuration to use different color
attributes.

An environmental variable named "EM5250" is used to control whether the oper-
ational mode of the 5250 emulator is full screen or text window. By default,
the operational mode of the 5250 emulator is full screen. The environment
variable "EM5250" must be set to "WIN" before the 5250 emulator is started to
place the emulator in a text window mode. The following procedure must be
used to change the mode of the emulator.
1. Locate the Communications Manager command file named "CM2.CMD. This file
is located in the directory named "CMLIB" on the drive that was selected
during the OS/2 EE installation process.
2. Edit the file named CM2.CMD with a text editor.
3. Locate the line that contains "REM SET EM5250=WIN". This line will be
immediately after the line that contains "CALL SETCMTD".
4. Delete the characters "REM " so the line now reads "SET EM5250=WIN".
This will set the environmental variable named EM5250 to a value of WIN.
5. Save the file named CM2.CMD that was just changed in the same directory
with the same name. The Communications Manager will have to be stopped
and restarted before this change will take effect.
If the operational mode of the 5250 emulator is desired to be changed back to
full screen, edit the file described in the previous procedure and add the
characters "REM " to the beginning of the "SET EM5250=WIN" statement. Again,
restart the Communication Manager to have this change take effect.

BATCH CONFIGURATION UTILITY
This version of the Communications Manager Batch Configuration Utility
(BCU) has been enhanced to allow the "Response timer intervals" parameter of
the NETBIOS profile record to be updated with the BCU. The "Response timer
intervals" parameter is the 8th field of the NETBIOS profile record and is
described below. Refer to appendix L of the System Administrators Guide,
for the other 7 fields of the NETBIOS profile record that may be updated
with the BCU.
________________________________________________________________________
Field 8: Response timer intervals
Field length: 2 characters
Required/Optional: Optional field
Comments: Specifies the time period, in ticks, to wait
for a response to LLC type 2 I-frames. Valid
values are from 01 to 10.
