Not really python anymore, but it's actually '+++' (three plusses) if
_I_ remember correctly. 8-)  And I'm pretty sure it's longer than
100ms...but this is just my guess from waiting for the 'OK' after
sending.  Maybe 500-800ms.  In any case, 'OK' should appear after some
time of no activity after sending '+++'.
