Subject: GRINOS v0.2s released

I am going to start an FTP upload of the new GRINOS-S.ZIP to WB6NIL as
soon as I am done typing this message.  This version has significant
enhancements, including:

-- A major bug fix caused by an incompatibility between the old and new
   Borland C compilers, in collaboration with NOS replacing a library
   function or two.  This caused TMP##.$$$ files to be created but not
   deleted.  This bug has been repaired, but at the cost of no longer
   supporting the user option to explicitly specify the directory to
   be used for temporary files.  All temporary files will be created in
   the current directory.

-- Correction of a stack framing error also related to the use of the
   new Borland C compiler.  This may have been responsible for the
   problems seen with the garbage collection routines for NOS memory.
   I am still not confident of the garbage collection code.

-- Auto detection of machine class.  The "isat" flag should now be set
   correctly for the type of processor found during initialization.  As
   I explained earlier, it is now required that the "isat" flag be set
   correctly for proper hardware interrupt handling, and this will
   relieve most users of the need to worry about it.  The "isat" flag
   can still be changed manually with the "isat 1" or "isat 0" commands
   for cases where the auto detection fails for some reason.

-- Memory efficient mode now defaults to enabled.  I have already
   recommended the use of efficient mode, although it can still be
   changed by command.

-- Enhanced reporting of information with the "memory status" command.
   Efficient and circular modes now show as enabled or disabled, and
   the current memory threshold is displayed.

Remaining known bugs:

-- I still have not fixed the problem with shelling out to DOS or the
   mailer in the first ten minutes or so before NOS has stopped calling
   for more core.

-- Memory garbage collection may still be broken.

Immediate future plans:

-- A "tcp blimit" command that would provide a maximum backoff.  There
   has been substantial demand for this feature.

This version is designated KA9Q 910531/PA0GRI v1.6h/N1BEE 910612v0.2s.
This is a beta-test release.  That means it should not be used on
unattended switches.
