If REPRESENTATIVE CLAUSES for interrupt vector addresses are supported
by your compiler then you could write your own charactor I/O interrupt
handler via Ada Tasking.  See REPRESENTATIVE CLAUSE in the green book.
This would be a way to keep all your code Ada, i.e. not linking to
any foreign language objects (this would make the DoD happy).  But I have
yet to find an Ada compiler where REPRESENTATIVE CLAUSES for interrupt 
vectors are supported.  Think of the Real-Time possibilities with High-Level 
language programming if it were implemented.
