And i downloaded the latest version of FTDI driver. Now I tried to use terminal software that kramer provided me. It's quite handy. i can easily change the parameter that I want. As I send the the command, I choose the ASCII mode. and I send "hello" . Inside the window, there displays three prompts ">>>". Also I checked the dec number it displays "62 62 62". But i can't get anything from the printing header. Any suggestion is welcome. Thanks. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=254803#m255052 Need assistance?
