It takes some digging, but the protocol level of UUCP *is* documented.  There
is a mailing list for people interested in reimplementing uucp in the public
domain, and the protocol description has come out over it.  I have also sent
it out to several people who have asked the net for it.

To get on the mailing list, send mail to ihnp4!akgua!ucf-cs!ki4pv!tanner.
So far only three issues have been mailed to this list, but I expect that
with uuslave, the traffic will pick up substantially.

I am hacking uuslave.c to actually run on my Sun Unix system and talk
to my uucp (I have multiple modems, so uucp can call "out" to uuslave).  So
far it compiles (some system V-isms needed ifdeffing for 4.2BSD) and
with some debugging has gotten through initialization of the uucp link
and a "hang up?" "yes" transaction.  The original code from the BBS
does absolutely NO error checking whatsoever.  A bit gets dropped, it
doesn't care.  I've added almost full error checking so far, added lots
of comments, and restructured the code so it can be read in 80 columns and
understood.

It seems to be having trouble with data transfers though; it has fixed,
funny ideas about packet acknowledgements.  That part of the code needs
to be generalized to match the protocol, rather than having upper level
code wait for specific packet formats.

When this version will actually send and receive a data file with Sun's
UUCP, I will post the revised sources to net.sources.  (Mod.sources
would be too slow, since a lot of folks are interested; and I'm sure
the code will evolve quickly anyway.)

I think that we should try to keep a single set of C sources that run UUCP
on all machines.  Take C-Kermit as an example.  I hate having seventyleven
different versions of things, with slight changes and typos, for different
machines.  It will be a lot easier to keep track of the evolution of this
beast with #ifdef's in the mainline code, or a separate "system dependent"
module (one per system) for system dependent code.

I am willing to act as a clearing house for C versions of uuslave that run
on different systems, in order that there be some center to the chaos.
I will only accept versions which have actually been tested and run
against a Unix uucp though.  I don't want to go to the work of merging
in changes that don't even work yet.  If you send me a version, please
specify what machine it ran on, the configuration of the machine (e.g. opsys
revision, funny peripherals), what Unix site it was tested against, and what
version of Unix and uucp the site runs (if you know).

I will post the uucp protocol description to comp.mail.uucp.  See you there!

Well.  Sounds good to me.  If YOU have the documented protocol for UUCP, be my
guest and post it.  It certainly has been my experience that NO ONE has ever
responded to my request for information.  Maybe you are a first...

I have what I consider a 'hackers' view of UUCP.  That means, the information
I have has been gleaned through use of UUCP's debugging facility, as well as
any other source of information I could find.  Undoubtedly yours must be better
than mine, so I won't post mine unless I don't see yours soon.

To date, 59 people have responded to my offer of posting UUCP documentation.
I hope that you can supply those 59 people with the information they are
looking for.  For that matter, I hope anyone can.  Its a big job.

Run on all machines.  Right.  Talk to lauren about that.  Ha.  :-)

Great!  I really was hoping someone with time would suggest something like
this.  Anyhow, my version of C source doesn't exist yet.  It won't until
I feel my Modula-2 version is working properly.  I'll send you mine later.

I'm waiting (here) with bated breath.

Well John, I appreciate what you are doing.  Really.  I wish someone would
have helped ME out before.  My goal in dealing with UUCP is to get something
that I can use.  It doesn't need to be perfect.  It doesn't need to work
with all systems.  If I can use it, then if it doesn't work, that's my
problem.  Maybe someone else out there feels the same way.

Anyway, more power to you.  I would love to see a pd UUCP show up.  I don't
like paying the price lauren wants, and I prefer source code anyway.  If
you do get a good UUCP going (and it's pd), I'd really like to see it
posted.  Who knows, maybe even Minix could join the net.

thanks guy...
