hmmm, from my reading of /etc/rc.d/rc.modules, ppp is being activated with a /sbin/modprobe ppp line in the file. When I listen to boot up messages I hear ppp-2.3.7 being loaded but interestingly in order to find README.linux I have to go to /usr/doc/ppp-2.4.1 directory. Hope this isn't a version conflict here. That rc.modules file came off the live/etc/rc.d/rc.modules file from cd 2 in the slackware set. An insmod ppp at command prompt followed by ppp-go gets the same error even though the insmod ppp doesn't generate any errors.
