If think "Open drain" is like open collector, the pin is floating when it's active, it needs a pull-up resistor or something, well, just copied the text from the datasheet. Playing with the EGPIO is very experimental and the consequences can be _any_, but hope that you already knows that -;) /Benny ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
