That made me suspect T/TCP in the : first place: ICMP and UDP datagrams passed the SLIP link. Only TCP : traffic caused errors at the link layer. : : Maybe it was a problem with Auto-VJ, it's not exactly reproducable now : and seems to be solved. I seem to recall from my recent exposure to the slcompress code that it assumes there are no options in use. I further recall that PPP and SLIP both use the same compression code. My recent reading of Stevens leads me to recall that T/TCP will use options somehow. Maybe that is the problem..... Warner
