TN3270.EXE/binary
TN3270 for LAN WorkPlace.
Upgrade from version 3.13a to version 4.04.
Significant changes in this version include support for the new
configuration file searching available in LAN WorkPlace for DOS 4.1 and LAN
WorkGroup 4.1, and enhanced display color control.
Installation instructions:
1. Go to the \TN3270 directory, and make a PATCH subdirectory.
2. Copy the TN3270.EXE file to \TN3270\PATCH and execute it.
3. Execute the INSTALL.BAT file.
Notes:
You must have the original TN3270 v3.13a software installed in order to
apply this update. If the patch program cannot find the original 3.13a
files, the new files will not be installed, and warning messages will be
displayed. If you have installed any other updates to TN3270, you should
remove them and restore the original files prior to applying this update.
The patch program will store the original files in the \TN3270\PATCH\BACKUP
directory. If you need to revert to the original files, go to this
directory, rename the UNPATCH.BAK file to UNPATCH.BAT, and execute the
file. The original files will be restored.
If you copied the v3.13a SNATERMK.STD file to SNATERMK as described on page
2-3 of the TN3270 for LAN WorkPlace User's Guide, you will need to do this
again after installing the v4.04 update.
Fixes and enhancements:
VM Help Screen:
**************
The VM help screen for T3270 Model 4 and Model 5 works correctly now.
Addresses of Snapdumps of Data:
******************************
The addresses of snapdumps of data are shifted to the left in the X15
trace, causing trouble with the "pstrip" program later on. This problem
has been corrected in this release.
Block Cursor Feature:
********************
A feature was added to support block cursor for the TN3270 emulator.
Block cursor can be selected by entering the command line option -BC or by
setting the entry #BLKCUR to "Y" in the SNATEXT file.
Port Numbers Greater than 256:
*****************************
This release corrects a problem where a port number greater than 256
would cause a connection failure.
Command Line Options (-red, -blue, -pink):
*****************************************
The -red and -blue command line options for the TN3270 command are no
longer supported. When these options are used, a message is displayed
instructing you to use the new color mapping feature.
Example:
C:> TN3270 -red -blue
Loading text
-red option is no longer supported. Use color mapping in COLORS.OCS file
instead.
-blue option is no longer supported. Use color mapping in COLORS.OCS
file instead.
Press any key to continue.
It is no longer necessary to enter the -pink command line option for the
TN3270 command; -pink is always in effect.
Underlined Fields:
*****************
Underlined fields in the 3270 emulation screens are now displayed in
reverse video. This enhancement applies to both color and monochrome
screens. For color screens the text is displayed in the foreground color
grey to distinguish the underlined fields from real reverse video fields.
Color Mapping:
*************
The color mapping feature allows you to assign new colors to the default
colors used by the 3270 emulator and the API visual mode.
The color mapping feature uses two files:
COLORS.OCS
PALETTE.OCS
These files are described in the following paragraphs.
COLORS.OCS - You can edit this file to assign new colors to the default
colors used by the TN3270 for LAN WorkPlace emulator. The entries on the
left (for example, oc_black, oc_blue, oc_green, etc.) in this file MUST NOT
be changed. These are the variables used by the TN3270 for LAN WorkPlace
emulation software. For the right side of the assignment, you can use any
color name defined in the file PALETTE.OCS (for example, blue, azure,
arcticnight, etc.). DO NOT change PALETTE.OCS - use it as a read-only
file. It defines the valid color names.
Sample Entries from the COLORS.OCS file
****************************************
* 3270 Assignments:
oc_black = blue
oc_blue = azure
oc_green = emerald
PALETTE.OCS - This file can be viewed by the user to determine valid
color names to use in the assignment statements in the COLORS.OCS file.
Sample Entries from the PALETTE.OCS file
*****************************************
000 black
001 blue
002 green
003 cyan
004 red
005 magenta
006 lime
007 white
008 arcticnight
009 aquamarine
.
.
.
061 rose
061 lightmagenta
062 yellow
063 brightwhite
*****************************************
IBM 3270 colors map to the COLOR.OCS oc_{color} values shown in
the following table:
IBM Colors oc_{color} Values
---------- -----------------
blue oc_lightblue
green oc_green
red oc_red
pink oc_lightmagenta
yellow oc_yellow
turquoise oc_cyan
white oc_white
black (background) oc_black
reverse video text oc_black
reverse video blue oc_blue
reverse video green oc_green
reverse video red oc_red
reverse video pink oc_magenta
reverse video yellow oc_brown
reverse video turquoise oc_cyan
In text mode (the only mode supported by Novell), the emulator
shows underlined fields in reverse video with a different text
color from normal reverse video:
underlined text oc_grey
underlined blue background oc_blue
underlined green background oc_green
underlined red background oc_red
underlined pink background oc_magenta
underlined yellow background oc_brown
underlined turquoise background oc_cyan
To change the IBM color, change the corresponding COLORS.OCS
oc_{color} assignment to one of the valid color names from the
PALETTE.OCS file.
Example:
To display IBM blue as aquamarine when using the TN3270 emulator,
edit the COLORS.OCS file and change the assignment:
oc_lightblue = lightblue
to
oc_lightblue = aquamarine
Using TRYCOLOR to view colors produced by assignments in the
COLORS.OCS file:
The utility program TRYCOLOR.EXE lets you view the colors produced by the
assignments in the COLORS.OCS file or by an alternate test file created by
modifying a copy of the COLORS.OCS file. Entering the TRYCOLOR command
with the -h option displays a help screen describing its use.
C:> TRYCOLOR -h
Program TRYCOLOR shows the selected emulator colors on the monitor.
The following options are valid:
-h............ to obtain this help text
-f filename... to process a specific color assignment
file. Without the -f option the standard
color assignment file, COLORS.OCS, is used.
Examples:
C:> TRYCOLOR
*******************************
TRYCOLOR Assigned Color Display of Assigned Color
oc_black = blue _________________________
oc_blue = azure _________________________
oc_green = emerald _________________________
.

*******************************
3270 Datastream Attributes:
************************
Rather than rejecting the 3270 datastream attributes "Character
Set" and "Transparency," the TN3270 product ignores these
attributes for a text mode terminal.
The -nocolor Option:
*******************
The -nocolor option works correctly now with an Orchid VGA board
and a monochrome monitor.
Orchid VGA Monochrome Monitor:
*****************************
The Orchid VGA monochrome monitor now supports a 327x Model 5
terminal.
The -DM and -DN Command Line Options:
************************************
The -DM and -DN command line options can now be entered with or
without a space (that is, -DM and -D M are both valid, also -DN
and -D N are both valid).
Image Data Processing:
*********************
This release fixes a problem in the image data processing engine
where image data was all being painted on one line on the screen.
The -nocolor Option:
*******************
This release adds the -nocolor option to T3270 for forcing
monochrome mode. This option is more effective for CGA, EGA, and
VGA monitors than the -DM option.
Screen Painting:
***************
Screens are now painted correctly for all CRT models upon a
session change; that is, with the right number of lines and
columns. This also fixes the problem of a PC soft wait, when
attempting to forward tab on a screen with the number of lines
set incorrectly.
Specification of an IP Address on the Command Line:
**************************************************
This release adds support for specification of an IP address on
the command line for TN3270.EXE for PC-NFS, 3Com, and HP sockets.
Lightpen Selection:
******************
Lightpen selection occasionally locked up the keyboard,
necessitating a keyboard reset by the user. This problem has
been corrected.
