I have more or less the same reason to use SLIP.
It's a simple dedicated line (IP-only) between my router and an Portmaster
on a fixed line.
No reason to do anything as complicated as PPP: no logins, no IPX .....

But am I to understand that running slattach creates the sl0 device?? by
something like 'ifconfig sl0 create'?
Or is slattach just loading the module which makes sl0 appear?
