Like I said, if you only need Tx and Rx lines, its even simpler ... just the tranciever plus 2 caps and a resistor (and power). The lack of triviality comes when you need the other lines (and the complexity there comes from both the hardware and the driver required). - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
