Has anyone managed to configure SLIP to work on a Pyramid (90xe, OSx4.0). After a bit of hacking into the sun/vax version I have now found that it uses IFF_ROUTE which has been removed from net/if.h and the bit reused for IFF_LOOPBACK. Please e-mail me if you have SLIP running on a Pyramid, explaining what you did to get it going (and what sort of performance we could expect if it were running ((and how easy it is to interface the Pyramid supplied higher level packages to it))).

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. <csg>
