TalkThru for OS/2 -- Version 2.3
This document contains release notes for version 2.3 of
TalkThru for OS/2.
---------------------------------------------------------------------------
Version 2.3 Highlights:
o TN3270
A TN3270 Terminal protocol has been added to the product.
Refer to the separate documentation for more details.
o Printing
Print destination can be set on a session by session basis.
It can also be changed by AUTOPILOT or EHLLAPI.
A C example of this would be:
USHORT CLimFunction = PCB_SEND_KEY;
USHORT Size = 33;
USHORT ReturnCode = 0;
hllapi(&ClimFunction, "@@TALKTHRU SET_LOCAL_PRINTER LPT3",
&Size, &ReturnCode);
An AUTOPILOT example of this would be:
send "@@TALKTHRU SET_LOCAL_PRINTER LPT3"
o Capture
The Terminal Capture facility has been modified to write
its internal buffer more often. This makes it easier to direct
capture output to an OS/2 pipe.
o EHLLAPI
A TalkThru specific extended call has been added to EHLLAPI to
retrieve Terminal Button Bar information.
EHLLAPI function call number 5011 ...
In the samples directory, there is a program that will
demonstrate the new EHLLAPI Button call. The program is
TEST5011. The source code and make file for this program
are also supplied.
Support for the undocumented Query Extended Status option
of EHLLAPI function 104 (PM Window Status) has been added.
This option is used by the CMMouse product.
Refer to separate documentation for more information.
o Carrier status on direct connections
An option has been added to the device configuration dialog
that enables the emulator's connect/disconnect status to
reflect the state of carrier in direct connections. The
default is to ignore carrier in direct connections.
---------------------------------------------------------------------------
Version 2.2 Highlights:
o Terminal Emulation Performance Improvements
Terminal sessions with high speed connections (TCP/IP, NetBIOS,
fast modems) can display nonscrolling data 2 to 8 times
fasterthan previous releases. Actual speed improvements
depend on the terminal protocol, displayed data format,
CPU speed, and speed of the connection.
o Review Window
A Review Window has been added. The Review Window displays
text that has scrolled off the top of the terminal screen.
The window will display the text in the same format (color,
font, etc.) as it appeared in the terminal window. Up to 100
pages of text may be retained. Selected text may be copied
from the Review Window to a file, printer or clipboard.
o DDE Support
Dynamic Data Exchange (DDE) is a standardized protocol for
exchanging data and commands between applications running
under Presentation Manager and/or Windows. TalkThru supports
DDE as both a client and a server using commands in the
AUTOPILOT script language.
o REXX Support
An EHLLAPI interface for REXX has been added that is
compatible with IBM's Communications Manager's SAAHLAPI
interface. In the SAMPLES directory, there is a REXX
command REXXHLPI.CMD that will allow you to see how EHLLAPI
calls can be made in REXX programs. You may also directly
call REXX programs from the Phone Book or Terminal Emulator.
o ZMODEM Restart
Support for the ZMODEM automatic transfer restart facility
has been added.
o CID Enabled Installation
TalkThru's installation has been CID enabled. Configuration,
Installation and Distribution or CID is a term used to
describe the enabling of OS/2 based products to be installed
and configured in a LAN environment with little or no user
interaction.
o AUTOPILOT Enhancements
In addition to DDE (mentioned above), AUTOPILOT has been
enhanced to support larger arrays ,icon button controls, and
user/system/3rd party written DLLs.
o Modem Support
The list of directly supported modems has been greatly
increased. In addition, modem configuration can now be
done at installation time.
---------------------------------------------------------------------------
AUTOPILOT WRITE Statement Enhancement
The AUTOPILOT WRITE statement has been enhanced to allow the option
of writing the internal buffer to the file/device after each WRITE
statement (the default is to write when the internal buffer is filled
or when the file is closed).
This feature makes it easier to use AUTOPILOT I/O with OS/2 pipes
and devices such as COMx.
To enable "writethru" mode, use the optional USING clause
in the OPEN statement:
OPEN <filespec> FOR <mode> [USING <options>] AS <filenum>
where <options> may be:
"writethru=y" -- Write to device after each WRITE statement.
"writethru=n" -- Write to device when internal buffer is filled.
The default is "writethru=n". When "writethru=y" is specified,
file output will be slower.
---------------------------------------------------------------------------
Instructions for using CMMouse with TalkThru
CMMouse will coexist with TalkThru only if the following rules
are applied:
1. TalkThru must be brought up before CMMouse. If CMMouse is brought
up first and then TalkThru is asked to be loaded, you will receive
a TalkThru '0002 Controller Application Error' and TalkThru will
not load. (If TalkThru and CMMouse are started in the STARTUP.CMD
file make sure TalkThru is completely up before running CMMouse).
2. TalkThru sessions can be either closed or opened (windowed or iconized)
when CMMouse is started. If TalkThru EHLLAPI sessions are only created
CMMouse will fail with an Initialization error on the Window Handle.
3. CMMouse MUST be taken down BEFORE TalkThru. TalkThru will not
unload unless this is done because CMMouse is using the TalkThru
EHLLAPI DLL.
