I am attempting to write a communications package that installs itself
(sets up interrupt vectors, buffers, etc.), invokes the application program 
that uses it, and cleans up when the application terminates. I have been
through the Microsoft documentation, but cannot fathom the arcane
references to "releasing" memory for use by the called task. I also
need to find a reliable way of passing the (actual) addresses of the
communications routines to the application, so they can be called from
there. (I was considering using interrupts, but became concerned that
the code might not be portable).

Does anyone on the net have experience with this sort of problem? If so, 
please reply by mail and I will organize and post the results.
