Hello.

1. Proces_Alarmu.Start -> Yes OK!
2. Proces_Alarmu.Stop -> Yes OK!
But
3. Proces_Alarmu.Start - Why does not start again exercise?

task Proces_Alarmu is
      entry Start;
      entry Stop;
   end Proces_Alarmu;

task body Proces_Alarmu is
   begin
      accept Start;
            loop
             select
                accept Stop;
                exit;
         or
            delay 1.0;
            end select;
put("test");
      end loop;
