3B15, SV 2.1.1, add SLIP ?

[Charles Bland]

	We are running Sys V 2.1.1 on our 3B15, and want to add SLIP ports.
We have the hardware, but so far, it looks like we need to recompile the
kernel to add SLIP. Really ? Isn't there an easier way (kinda hard to do
WITHOUT sources   :-)) ?  

Thanks in advance.
