Sure. It will be a supported product in OSx 4.4, now in beta test. Harrass your salescritter if you want to be a beta test site. I suspect that the problem you had porting the Sun/VAX version to OSx 4.0 is that OSx 4.0 is 4.3BSD; it sounds like you had the 4.2BSD version of SLIP. Performance has been pretty good; we had to make some minor modifications to get dropped packets on the source side to work properly. (Otherwise we occa- sionally got long TCP timeout delays.) rlogin over a 19.2K SLIP line is not visibly different from rlogin over Ethernet. Of course, when you get several people doing cat /etc/termcap at the same time, it gets a bit sluggish. :-) We've also just started running SLIP on the Telebit TrailBlazer between here and Ames; interactive really stinks (1 to 4 second echo delays), but that's because the TrailBlazer is half duplex. File transfer is better. We'll be compiling (and posting) specific numbers as the project moves along.
