I have the basic code done, passing all of Michael=E2=80=99s = 215 reassembly code packet-drill scripts and am just moving in to test it on machines for = data corruption. Hopefully by the end of the week I will have something fairly stable = that I can put up in a review.. Best wishes R -------- Randall Stewart rrs@netflix.com 803-317-4952
