I realize I'm in the wrong newsgroup (what's the right one?), but I
figured one of you might have the expertise I need, or might be able
to point me to it.

Simply stated, I am researching the possibility of application to
application communication between an IBM-compatible mainframe and a
large number of IBM PC's; IBM calls this APPC (advanced program to
program communications). I am not interested in any kind of
host-to-terminal communications, nor in file transfer protocols.

LU 6.2 seems to be the way to go, but I'd like to know what's
necessary on the PC end, especially how to implement PU 2.1, which
together with LU 6.2 is necessary for APPC. Has anyone developed
function libraries for this that I can link in with the applications
I'm developing, or do I need to look at cards or "black boxes" of some
sort (maybe something that does RS232 on one end, LU 6.2 on the
other), or do I need to network the PCs first, with the SNA gateway
functioning as the PU 2.1?

E-mail responses preferred. If there is a better (or equally good)
group for this, please let me know as well. Thanks.
