GNAT serial comm under FreeBSD - PROGRAM_ERROR raised

[darek <darek.maksimiuk@gmail.com>]

Hi All,
  I have installed the AUX compiler from http://www.freshports.org/lang/gcc-aux/ (gcc version 4.9.2, 20141030)  on my FreeBSD (ver. 9.2, amd 64)  machine. The PC needs to talk to an external device via the serial port. The program compiles without any problems but at  the run-time, I got the following exception:

 raised PROGRAM_ERROR : Serial Communications not implemented

If this is a feature (due to any imaginable issues), is there any other package that  handles the serial communication under FreeBSD?

BTW, the status of the port on http://www.dragonlace.net/ is described as a "perfect". 


Cheers,
  Darek 


Test program:

with Ada.Text_IO; use Ada.Text_IO;
with GNAT.Serial_Communications; 

procedure TestSerial is

   package Serial_IO renames GNAT.Serial_Communications;
   
   Port_ID : Serial_IO.Serial_Port;
   Port_Name : Serial_IO.Port_Name(1..10) := "/dev/ttyu0";

begin
   
   Put_Line("Test  serial port");
   Serial_IO.Open(Port_ID,  Port_Name);   

   Serial_IO.Close(Port_ID);
   
end TestSerial;
