Re: What way to connect AS 236 system to NT 3.51 or 4 MS Network without using SNA SERVER?? -- MIDRANGE-L

Dear Philippe,

The AS/36 model 236 consists of AS/400 RISC processor based hardware running an 
updated version of the original S/36 operating system known as SSP. Because of 
the underlying AS/400 based nature of an AS/36, you gain some added 
capabilities that were not available on the original S/36. There is a PRPQ 
available for the AS/36 model 236 known as the DOS Client for SSP PRPQ. This 
PRPQ effectively adds Client Access/400 for DOS capabilities to your AS/36 
including the QPCSUPP subsystem. 

One of the significant benefits of the Microsoft SNA Server software product is 
its ability to receive information from an IBM Midrange host using SNA 
protocols and then allow LAN clients to access the information using TCP/IP 
based applications (TN5250 and FTP). The current TN5250 support available in 
Microsoft's SNA Server product requires the QPCSUPP subsystem to be available 
on the target IBM Midrange host to which the TN5250 clients would like to 
establish a connection. Adding the PRPQ referenced above provides the necessary 
subsystem support on your AS/36 model 236 machines to allow the SNA Server 
software TN5250 support to function correctly. If you were to investigate 
converting your client applications to TN5250 for display emulation, you would 
be able to use 32 bit clients.

File transfer in this environment can be accomplished using FTP from the client 
to the SNA Server software. The SNA Server product includes a feature called 
AFTP (APPC FTP) which can receive a standard FTP request from a client and then 
forward the request to the target IBM Midrange host using this unique AFTP 
capability.

ODBC access is supported by using the Client Access for DOS router with SNA 
Server instead of the default token ring 802.2 link driver. The DOS Client for 
SSP PRPQ also includes the PC diskettes with the DOS Client software for your 
Win NT machines. The Client Access for DOS program includes a software program 
called a router. The IBM WAN protocol used on the AS/36 includes some of the 
broadcast functionality of TCP/IP. The router program allows a particular Win 
NT server station to locate a particular IBM Midrange host and begin a WAN 
protocol communication with the target host by using IBM's version of 
broadcast. In order to perform the SQL communications with the AS/36, it 
appears that you will need to be using this router program on your Win NT 
machine. You will need to use the router software to enable the communication 
with the AS/36 via the token ring card installed in the Win NT server station. 
You can then configure the SNA Server software to work with the router program 
to make its connection to the AS/36. In this way, you can have complete SQL 
access from all Win NT Backoffice software packages to the AS/36 database. 

The instructions for configuring SNA Server software to use the Client Access 
for DOS router can be found at the following URL:

As far as I know, the SNA Server product has not yet added TN5250E printing 
support. Printing can therefore be supported with SNA Server compatible print 
client software. LogNet, MPI, and Praim are some of the vendors that offer such 
software print clients. It would probably be possible to create one print 
server station that could support the printing needs of all of the AS/36's in 
your customer's network.

I hope some of these ideas might be useful for your customer.

Best Regards,

/Paul

Subject:        What way to connect AS 236 system to NT 3.51 or 4 MS Network 
without using SNA SERVER??

I have a customer who use an AS/236(in fact around 10 systems installed) and
want to change their connection via SNA server and Netsoft 236, to another
system full 32 bit.
Actually the AS /236 is connected to SNA server station via TKR attachment
in AS and NT Server station, and the NT Server station is connected to
network via Ethernet Attachment.
Stations use Netsoft 236 emulation on SNA server link . Those programs are
16 bit and are not compatible with NETSOFT  32 bits for AS 400.
Is it a product to get full functionality of connections (i.e.: display
emulation, printer emulation, data transfer: upload and download , and or
ODBC driver to permit for instance MS ACCESS to see the data situated on AS
236)??
For budget reasons my customer do not want for the while to upgrade to AS436
if this is possible , neither to AS 170.
Tks for answer(s)
Philippe.
