The problem is that you can't cram a signal moving at 10 Mbps through a radio interface designed for 256K, even if it is bandwidth limited to 256K. I'm hoping the 3C503 is ancient enough that I can slow it down by yanking it's 20.0000 MHz crystal oscillator and feeding it a lower speed signal. I'm going to walk them down to see just how far I can go. After all, 2 Mbps isn't bad, it just requires a little more work. -- Kris Kirby ------------------------------------------- TGIFreeBSD...
