It probely  just trow them away, i think the reson why is not a problem 
is that besides being zero terminated the the messages that i sent are
requered to start with '$', Anyway i will, ofcourse change to
string'write

Not for any partikulari reason.

When i started developing job i tried with ASCII.NUL
things didn't work out(surely for som other reason);
they did when i first was using character'first.
(also surely for som other reason);

Are there any reason why ASCII.NUL should be better;

ASCII.NUL are defined as Character'First;
