Although its been a while since I fiddled with GLADE, it seems to me
that
the DA is exactly what you are asking for. Make your Monitor program
the
main partition, and the embedded software your remote partition. (Note
that
partitions can reside on the same machine or be truly remote.) GLADE's
configuration language takes care of the RPC calls that are used start
the
remote partition when the main partition begins execution, and the RPC
calls
that shut it down. Communication between the partitions is accomplished
via
Ada.Streams, simulating the serial data stream that your embedded
hardware
normally sends.

Obviously its not as easy as my paragraph above makes it sound, but
looking
at the GLADE sources might be an excellent resource.
