In most UUCP connections using error corrected modems  that I have had to
debug, the most common problem has been flow control.  And the most common
flow problem is(was) that one or more modems are eating XON/XOFF characters.
                                                                              
Make sure you have XON/XOFF pass thru on, on both modems.  Sometimes
your sys admin will be reluctant to do this, but it will work.  If the
modems eat these characters, uucico will fail fail fail.
