1/15/85?? - Version 1.1 (IOP)
  Fixed the routine "int_all" which interrupts all tasks on
  a given terminal.  This fixed some problems associated with
  typing control-C, etc.
  Also, the auto-sizing code did not work properly for more
  than 20 terminals.

2/17/85 - Version 1.2
  Fixed a timing problem involved in control-C aborts (they
  are difficult, aren't they?).  In this case, a task was
  processing a "request for space" transaction and got interrupted
  by the "interrupt all tasks on this terminal" transaction.
  Interrupts were only being honored when the task went to
  sleep and in this case were ignored.  Thus you ended up
  with some space pre-sold for a terminal and the associated
  user of the space (on the UniFLEX end) was blown away.  Depending
  on the buffer sizes, this could lock the terminal up permanently.
