If that doesn't work then you might want to put an inverter (MAX232) between the SX and your PC as it may not like the voltage out of the SX. If you use an inverter you'll need to change to T9600. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=195343#m195347 Need assistance?
