I rewrote my scripts to output ASCII, made the proper stty settings, and it works great. For those of you that want to send serial to a SX from a linux box, I have a sample PHP script that uses PHP Serial class by Rémy Sanchez . I've attached that class, and my sample programs if interested. -Craig ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=294581#m295227 Need assistance?
