Serial Line IP (recently discussed on this list in another context) runs fairly well over Trailblazers. There are some inefficiencies under some conditions because minimum-length TCP packets fall into a length range that the Trailblazer isn't optimized for. Thus, TCP acks cost more bandwidth than one might expect. SLIP is described by RFC 1055, and commercial implementations are available from FTP Software (for DOS PCs), cisco (terminal servers/routers), Encore (terminal servers) and Spider Systems (???). Public-domain source code for 4BSD Unix exists, too, and as far as I know, all the implementations interoperate correctly. Efforts are underway to develop a more general serial line protocol to replace SLIP, but for now, it is a reasonable choice. James VanBokkelen FTP Software Inc.
