Re: Where is my SLIP interface
Don't ask why, but running 'slattach -l /dev/cuaa0' works No modem is connect now so it could be the -l stuff. And slattach would be waiting for my modem to signal things. it created sl1 but who am I to complain.

PPP (and presumably SLIP) interfaces are now cloned on request rather than created statically. Nice suggestion, but no sigar. See log below.
