I started with a similar slow server "lapl" which the 7.0BETA3 installer on install client "norb" failed to contact, then I switched to a fast server "fire" that also failed. Hosts "lapa" & "lapl" below work, so a reference to test PL-IP links with: HOST RELEASE PROCESSOR fire 6.2 AMD Athlon(tm) 64 Processor 3000+ (2010.06-MHz K8-class CPU) lapa 4.11 Pentium II/Pentium II Xeon/Celeron (267.27-MHz 686-class CPU) lapd 7.0-BETA3 Pentium/P55C (166-MHz 586 CPU) (no ppc yet, config prob) lapl 4.11 Pentium/P55C (120.27-MHz 586-class CPU) loft 6.2 Pentium II/Pentium II Xeon/Celeron (334.09-MHz 686-class CPU) norb 7.0-BETA3 Intel Pentium (P54C) (586-class), 133.65 MHz, id 0x52c Links: lapa-loft, & fire-lapl dont work. ( Host fire (X server) display same sticky mouse latency I've seen previously on a working FreeBSD plip/slip though, so some activity on that cable, it's trying even if not a working IP link. (No lpd of course, 3 PLIP cables, all tested OK on lapa-lapl) I think PLIP in much or all of FreeBSD-[5-7].* is defective. http://www.freebsd.org/cgi/query-pr.cgi?pr=113856 http://berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/gen/share/man/man4/lp.4.REL=ALL.diff http://berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/gen/share/man/man4/plip.4.send-pr.ignore http://berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/jhs/sys/dev/ppbus/if_plip.c.REL=ALL.diff Probably time `man plip` is marked as Dead, until fixed.

Thanks, Some time I'll hope to look in /usr/src/sys/ dev/ppc & modules/ppc if no one else does. -- Julian Stacey.
