This is your problem.  Uucp sends raw binary data.  Unless the compression
scheme used by netnews guarantees no XON/XOFF characters in the data
stream, the data file being transferred may trigger flow control
on anything in the data link that's checking for it.  Even if you
are sending plain text, the packet headers used in the uucp protocol
will eventually generate an XOFF (control-S) character, which will stop
the whole works.  Set everything that's settable for no XON/XOFF,
and it should work.  Any data errors will be caught and corrected
by the uucp protocol.
