Time to experiment a bit. So far so good. If I change add "set choked 10", I am not able to hang the usb port like I was before. The value is quite a change from the default 120 seconds, but still 10 seconds to transmit (for my application anyways which is a modem backup if the DSL fails) is adequate. I am going to let it run 48hrs to see if it still stable. On one device, I am running just continuous pings, and I am kicking off the connection every 10 min from the terminal server. On another machine, I am running it with random bursts of data and kicking it off every 5min. ---Mike
