This  same  problem  was  discussed  recently  (and  solved)   in
comp.mail.uucp,  comp.sys.sun.admin,  and comp.sys.sun.misc under
the subject "Weird! Sun can't UUCP to other  Sun  except  without
password?" I'll repost the final summary below after a quote.

The mystery is solved, thanks to all the people who replied.

I needed to transmit the password using a non-default parity set-
ting.  I  learned  my  uucico  process  understands  a variety of
pseudo-strings which can be included in  the  chat  scripts.  The
special  strings  cause uucico to change the configuration of the
transmitting serial device. My chat script now uses the  "P_ZERO"
string. I ended up with a chat script which looks like this:

   host time device speed phone "" \d in: foo word: P_ZERO "" bar

I learned that all pseudo-strings  must  be  "stand-alone"  send-
them  strings. This usually requires an associated expect-nothing
string (""). In the chat script above, the "P_ZERO" string is in-
terpreted  by uucico causing it to change the transmitting parity
before the password (bar) is sent.
