Is your ISDN gateway box doing *anything* but route packets? My gateway box was running a 28.8K modem link to the net (it's got a 56K Frame line now) so whenever I downloaded at home it took a huge hit w/out problems. But, it doesn't do anything but route packets so it never has a problem since it's the *only* thing running on the computer. It's hard to get overflows when the only processing the computer does are serial/network interrupts. :) Nate
