Some obvious things to try.
  1) turn on _complete_ logging, 
     *show* the log results of 'doing things manually'  where it works
     AND the  results  of the scripted run, where things are garbled.
     (in both cases, show -everything- from the beginning of the session.
      what happens -before- the problem shows up is significant_
  2) see what happens with just a -single- command to the TNC where the 
     string of 'telltnc' calls is?
  3) try a 'sleep 1' after every lineout, and/or 'telltnc'
