You seem to be assuming I am using the thin layer directly in my
program, in actual fact I have a thick layer:

procedure Put(Handle : Handle_Type; Item : in Byte_Array) is

  Item_Buffer : aliased Buffer ...;

begin
  ...
end Put;


I believe this does require a copy.

I want a thick layer binding, so I have to option available to port
code to Linux, should the need either occur, just be changing the
serial IO module.

I seem to remember that I encountered problems doing things as simply
as you suggest, but I can't remember why nor can I imagine why - I
will try it again and report back here with details of any errors
encountered.
