   Have I got a deal for you...

   I'm the developer of the ZModem file transfer protocol implementation used
in the Opus BBS system.  ZModem is about the best protocol available for micros
these days, and users worldwide have been enjoying its use on Opus for some
time now.  But I have a problem... my BBS is Amiga-oriented, not PClone-
oriented like most other Opus boards.  And there are no PD/Shareware ZModem
capable terminal programs available for my users to use!  Online! 2.0 added it
in, sort of, though they didn't do a very good job of it (forced ACKs every 1K,
no resumption of aborted downloads). But most of my users use one of the
various PD/Shareware terminal programs out there, like Handshake or Comm.  It's
very frustrating to have gone to all the trouble of adding ZModem to Opus, only
to have it sit around unused on my own board.

   I keep thinking about adding my code into one of the better Amiga terminal
programs, but I never seem to be able to find the time.  And the best I could
hope to manage would be adding it into a single PD program, which would then
age and become obsolete.  What I'd really like is for ZModem to get added to
SEVERAL of the better programs available, and for those programs to be living,
evolving programs actively supported by their authors.

   So, here's the deal.  I have available on my BBS the complete source code
and documentation for the original external Opus ZModem driver.  This driver
has since been integrated into Opus itself, and so is no longer needed as an
external driver, but was well-tested and widely used.  It's a relatively clean
implementation, with all extraneous code removed.  It should be fairly simple
for an Amiga programmer to port the bulk of the driver directly into their
terminal or BBS program.  I also have the complete ZModem spec and Unix source
available.  I would be delighted to answer questions and give support to any
Amiga programmer interested in porting my code into their software.  You still
do the work, but I help you figure it out.  Sound fair?

   Interested parties may call and download (or file request, if you have
FidoNet access) OZ_111.ARC (the driver) and ZMODEM.ARC (spec & Unix code).
I'd post it to the net, but it's around 200K total B-).  Any takers?
