I have noticed this frequently when calling Intel 9600ex modems from the 
USR Courier HST.  I'm not sure which modem is at fault (both ??) but I will
often get half a screenful of garbage before the session dies.

I have never heard of the v.32 standard including a 'sanitary' session
shutdown.  I would think that SOME noise would be unavoidable if the line
is simply broken.  On the other hand I can visualize some kind of
termination handshake which prevents it.  Anyway, you got me very curious
about it.
