S5R4 UUCP also has the ability to restart failed transfers.  This feature,
called Checkpointing (?), saves the data that was received properly and
the next time a connection is made, notifies the other end that x-bytes
were already received, start from there.  This may be very helpful when
transferring multi-megabyte files!  I don't have any details on the
implementation, but if anybody does, let me know!
