AlphaDDE 1.1 Release Notes
AlphaDDE allows a Windows client application to communicate with its topic
server on an AMOS host.
AlphaDDE has two main components: SOCKS.LIT on the AMOS host and
ALPHADDE.EXE on the PC. SOCKS exchanges ITC messages with topic
servers while ALPHADDE.EXE exchanges DDE messages with client
applications. SOCKS and ALPHADDE.EXE send and receive IP messages via
AlphaTCP on the AMOS host and the TCP/IP stack on the PC.
AlphaDDE 1.1 maintains all support provided by AlphaDDE 1.0. This version
offers several new features, and is significantly faster. It also has some internal
changes in identifying each PC for the AlphaCONNECT product.
NEW FEATURES
The new features are listed below:
•
•
•
•
•
•
Option to display the PIC code and maximum number of users authorized.
More ways to bring up SOCKS.
Larger DDE message size.
Simplified ALPHADDE.INI file.
Trace option on the AMOS host.
No AlphaNET needed if AlphaTCP is using the new LDV drivers.
PIC CODES
AlphaDDE 1.1 still requires a PIC code when you bring up SOCKS.LIT the first
time on the AMOS host. However, if you are upgrading from version 1.0, you can
use your old PIC code.
You can enter SOCKS/P at any time to display your PIC and the maximum
number of allowed users.
COMPATIBILITY AND REQUIREMENTS
Requirements remain the same as with AlphaDDE 1.0:
•
AlphaTCP 1.1 or later
DSS-10552-00, Rev. A00
Page 2
AlphaDDE Version 1.1 Release Notes
•
AlphaNET 2.3 or later (needed ONLY if Ethernet driver .LDV is not used)
•
AMOS 2.2C or later
•
A Winsock-compliant TCP/IP protocol stack on the PC
•
Windows 3.1, Windows for Workgroup 3.11, Windows 95, and later
versions.
However, the following issues should be considered:
1. You cannot mix AlphaDDE 1.0 modules with those of AlphaDDE 1.1:
ALPHADDE.EXE of version 1.0 on the PC will not work with SOCKS.LIT of
version 1.1 on the AMOS host.
2. The speed improvement is much more significant if AlphaTCP version 1.3
or later is used.
3. AlphaCONNECT requires both AlphaDDE 1.1 and AlphaTCP 1.3 or later.
HOW TO BRING UP SOCKS
There are four ways to bring up SOCKS on the AMOS host:
Through the system bootup .INI file:
Add the following items to your .INI file at appropriate places:
JOBALC
TRMDEF
SETJOB
SOCKS
SOCKS, PSEUDO, NULL, 100, 100, 100
SOCKS, SOCKS, 150K, SOCKS.JIN
(SOCKS alone needs 120K of memory. You will need more than 150K of
memory for large numbers of connections. Each connection requires about
6.5K of memory for buffering. SOCKS can support a maximum of 106
connections with a memory of 800K).
SOCKS.JIN looks like this:
:T
LOG SYS:
[your user name]
[password]
VER
SOCKS
AlphaCONNECT uses this method to bring up SOCKS.
Through CONFIG. file of AlphaTCP:
In the TCP: account:
1. Create a SOCKS.CMD file that looks like this:
DSS-10552-00, Rev. A00
AlphaDDE Version 1.1 Release Notes
Page 3
:T
LOG SYS:
[your user name]
[password]
SOCKS
2. Add to the CONFIG. file the following line after ftpd and telned
start SOCKS 150K
This will start SOCKS each time AlphaTCP is started.
Through terminal keyboard:
At any terminal attached to a job with sufficient memory, just enter
SOCKS. Only one SOCKS is allowed to run on each AMOS host. This is
useful with the Trace Option SOCKS/T described later in this document.
Through type-2 Virtual Connection:
After a connection is established via CONECT (or CTRM of AlphaLAN)
with sufficient memory, simply enter SOCKS to bring it up.
MAXIMUM DDE MESSAGE SIZE
The maximum DDE message size is now increased to 2048 bytes with
AlphaDDE 1.1, applicable to data packets going both from and to the PC.
ALPHADDE.INI FILE
With AlphaDDE 1.1, it is much simpler to create the ALPHADDE.INI file. There
is only one required entry and only one optional entry, as described below:
Required entry: [hostaddress]
This is the Internet (TCP/IP) address of the AMOS host on which SOCKS.LIT is
running. Either a pre-defined system name or a dotted decimal address is
acceptable. For example:
[hostaddress]
InternetName=192.245.218.14
or
[hostaddress]
InternetName=AMmainhost
Optional entries: [Configuration]
These entries contain information to control some of ALPHADDE.EXE actions.

TRACE OPTIONS ON PC
If you wish to monitor different activities and exchanges between your client
application, ALPHADDE.EXE, and the TCP/IP stack, you can activate trace.
However,trace degrades the normal operation of AlphaDDE and you should
NOT be use it on a permanent basis.
You can select trace options through the AlphaDDE window.
DSS-10552-00, Rev. A00
AlphaDDE Version 1.1 Release Notes
Page 5
From the AlphaDDE menu, choose Trace. A pop-up menu appears. Select Trace
Options. The window below will appear.
Select the desired option(s), then choose the OK button.
The trace is now on.
TRACE OPTION ON THE AMOS HOST
For debugging purposes, you can monitor different activities and exchanges
between your topic servers, SOCKS, and AlphaTCP by using the /T option. Run
SOCKS on a job attached to a real terminal with SOCKS/T. Trace messages will
be displayed on this terminal. Again, this trace option degrades the normal
operation of SOCKS, and should not be used on a permanent basis.
ALPHANET DEPENDENCY
If AlphaTCP is using the LDV driver then there is no need to have AlphaNET to
support AlphaDDE. This is true for an Eagle 550 system where the LDV driver is
being used and there is no AlphaNET software loaded.

TRUMPET DISCLAIMER
We include the Trumpet shareware Winsock stack as part of this release. Be
aware that if you use it, you must register it.

WINSOCK TCP/IP PROTOCOL STACKS
Here is a list of vendors of Winsock protocol stacks. Most or all of these vendors
also sell network utilities-- file transfer (ftp and/or tftp), terminal emulation (telnet
and/or rlogin), remote printing, etc.
Some but not all of these products have been tested with products such as
AlphaDDE or AlphaLAN.
AlphaDDE has experienced no problems to date with using Winsock stacks from
different vendors, but that does not preclude the possibility. This list is
included as a reference. No claim is made as to whether any untested
version will work.
