[ruby-talk:00212] Re: Get character with no wait

That suppressed echo of input, but didn't solve the problem.
Here is my code snippet, where s is a socket object:

system 'stty -echo'
   loop do 
   	j = getc()
   	if j != nil
   		s.putc(j)
   	end
   	m = s.getc
   	if m != nil
   		putc(m)
   	end	
   end
