I am glad a fix was found, but based on the LOGFILE entries and our
experience the problem was not on the Ultrix system side.  We talk to 13
or so other sites -- Ultrix systems and non-Ultrix systems -- using the
Ultrix-32 UUCP.  On our system as well as on some of the others, the uucp
login names are different but are all the same UID for different systems.
We have no problems.  I suspect the problem -- based on the LOGFILE
entries -- was in the USERFILE of the other system.  In fact, the problem
might be with a UUCP that didn't recognize system names of more than 6
characters.

Fred.
