I found where the problem is:
in newsmth(also free) only complet control(escape) sequence is processed.For some reasons, I sent the sequence using a for loop and this causes problem-----newsmth just abandons the esc key and takes it as a "[" and a "a".


I've fixed this problem in my code, and now it works find, thanks everyone.

P.s. I'm posting this article in matlab now:) and that's why I'm speaking English
