hmm.  how many lines were cut?  blogin is just writting to stdout which
is redirected to this file.  what i find odd is lack of an error, timeout
specifically.

could you telnet to the box, enter 'more off' (disable pager), then
'show config' and 'show config verbose', and finally exit.  if it
doesnt truncate; please send the portion from 'autolearn' on to the
unix prompt.
