A dedicated controller would have MUCH higher bandwidth than the <1.5mbitcapable on the DZ11. ;) It's the interrupt load that's the problem. It could TANK an 11/750. Didn't the DZ11 depend on the CPU for interrupts? Isn't that why say...the DHV11 had processors to offload serial processing to? -Dave -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
