      We noticed that we were only able to communicate once with a GSM module
      per session, if we powered down the module then the serial driver was
      broken until reset, no traffic or /proc/interrupts activity could be
      seen any more.
      
      Volker noticed it was provoked by a long "break" seen on the wire when
      the RX was not driven during powerdown, we discovered we could kill the
      serial driver just by forcing RX low extenally for a little while.
      
      I saw that the processing for BREAK in the driver gets too excited and
      clears down all set bits in USR2, including that a character is pending.
      This stops all further characters getting processed.
      
      The attached one-liner makes the serial driver immortal against BREAK.
