It is believed that there is a problem with the Ascends that Demon use
which leads to checksum errors. The Ascends have a fixed buffer of about
16k per connected user. If you advertise a large receive window, the
buffer can overrun and packets get dropped which screws the VJ
compression. I use a window of 7k which reduces the problem.
Note: the single Ascend buffer has to handle multiple TCP streams to you.
There is also another problem as I get checksum errors with novj, but far
less often.
