 Is there, is there, balm of Gilead? I have a feeling that the answer will
be "Nevermore", but... .  I have been trying to get three local unix
machines to send mail and files back and forth with uucp.  The machines are
connected via terminal servers - which act pretty much like a terminal
switch.  The problem is that the servers are too smart for their own good,
and they try to do flow control, autobaud, auto-parity, etc.  A major
stumbling block has been the complete lack of documentation on how the
internals of uucp work - ie what exactly is the "g" protocol, and which
ascii characters does uucp actually use?  What I am looking for is something
akin to the manual that I know exists kermit.  I have access to the source
for uucp, but neither the time nor desire to start wading through it.

 Is the lack of a generally distributed explanation of the protocol
considered essential to security on uucp?  It seems like a security system
which is based on the assumption that people will be too lazy to read the
source code is a pretty poor system - it won't foil any truly nasty folks,
and its a real pain for everybody else.

 Anyway, I would really appreciate it if someone would mail me a copy of
such a manual if it exists.  Lacking that, I've included below some bits of
debugging output which I am trying to comprehend.  Any hints will be
appreciated.

Many thanks in advance.
