I've read a couple of messages on this group about porting the IOC core
to other operating systems.  Thanks to the great work of others in
splitting the operating-system-dependent and
operating-system-independent parts of EPICS I've been able to write the
OS-dependent routines for RTEMS.  For the most part the EPICS calls map
directly to RTEMS directives.  

If there's anyone else out there that is interested in the RTEMS port,
I've put the routines on our ftp site:
ftp://skatter.usask.ca/pub/eric/RTEMS/EPICSosi.21Oct1999.tar.gz

Now for a request.  I'm having some difficulty figuring out which
configuration files I have to edit to get the RTEMS-specific routines to
build as part of an EPICS application.  I welcome any advice in this
area.

Here's some information from the RTEMS home page
(http://www.oarcorp.com/rtems/rtems.html):

      Priority inheritance and ceiling protocols 
      Homogeneous and heterogeneous multiprocessor systems 
      Responsive interrupt management 
      High level of user configurability 
      Reentrant ANSI C Library 
      BSD Sockets
