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.
