[comp.sys.ibm.pc] 3270/vt100 communication software library needed.

john@metavax.UUCP (John Mitchell ) (08/31/88)

I am looking for some pc software that will emulate a 3270 device as well
as a vt100, and will perform file transfers between an IBM/PC style 
machine and a host machine (IBM VM/CMS, IBM MVS/TSO, and DEC VMS).

Here is the situation, we have some existing software for the PC, and some
existing software that runs on mainframe machines.  We would like to 
provide an interface for our customers between the PC and mainframe
software.  Currently our PC software generates "transfer" files which the
client uploads to the mainframe outside of our software, our mainframe
software then accepts the "transfer" files as input.

We would like for this process to be much more transparent to the client.
Ideally, we would like to write some software on the PC that "knows" about
our mainframe software.  This PC software would get requests from the client,
perform some checking on the requests, translate the requests to something
that the mainframe will understand, send the request to the mainframe, and
return the results to the PC.

What we need, is a PC product, with a programmer interface from C, that will
be the buffer between our PC and mainframe software.  Our PC software would
call it with requests like "get this mainframe file" or "send this message
to the mainframe", again ideally this same interface should be usable whether
the mainframe is an IBM or a DEC or even a UNIX machine.  This may require
software on the mainframe side to handle that end of the file transfer.  It 
may also require more than one product to handle the different mainframe
protocols.

Now for the kicker, we would be willing to pay for such a product.  If you
know of any products currently on the market that sound like they might do
the job, if I'm thinking about this on too simple of a level and am missing
some major ramifications, if you've tried something like this before with
either success or failure, please send me e-mail.  I am not a regular reader 
of this group.  I'll summarize if requested and enough info is available to
summarize.
