I have used the changes that appeared in the pc532-src mail list to
get a new version of minix.  I have used that version for a while and
thought I should post my experience.

  a)  The patches went great, no problems.
  b)  The RTS/CTS for the rs232 lines was good.
  c)  I still had problems with the rs232 lines.  No characters were lost
      and the system did not crash, but it lost intterupts (I think that
      is what it did) and required more key strokes to cause previous ones
      to be recognized and sent.  It  was very pronounced when using kermit.
  e)  The system was generally more unstable than Bruce's kernel.  I had to
      reboot the system due to hangs etc about a factor of 10 times more.
  f)  The bpt trap did not return me to the monitor.  I don't know what it
      did.
  g)  Also, if kermit (or other software) opened a port that did not have 
      CTS asserted, you could not kill the process until CTS was asserted.

In conclusion, some of the changes were nice, but I have switched back to
the original distribution due to the high number of system hangs.
