Hello,

I just started to learn Ada and have been playing/working with Ada for
two weeks now.

I want to send a command buffer to serial port using florist's POSIX
interface but I have encountered problems in converting record to
POSIX.IO.IO_Buffer or Ada.Streams.Stream_Element_Array. How can I
overcome this problem?

package ABCD is

   type Command is
      record
          A : Character;
          B : Character;
          C : Integer;
          D : Long_Integer;
      end record;    -- total 8 bytes;

...
end ABCD;


POSIX.IO.write (File_Descriptor, Command, Length);

where 

   procedure Write
     (File           : in File_Descriptor;
      Buffer         : in IO_Buffer;
      Last           : out POSIX.IO_Count;
      Masked_Signals : in POSIX.Signal_Masking
                     := POSIX.RTS_Signals);

I have searched the CLA but do not find any solutions. Can you please
help?

Thank you.
