everything concerning SLIP seems to be out of date

[Björn König]

Hello,

I wanted to use SLIP to connect two machines with a null-modem cable, but I realize that all information concerning this topic seems to be out of date. First of all the device sl0 doesn't exist in 5.3 although there is a "device sl" in sys/i386/conf/GENERIC for Kernel SLIP. The manpage of sl contains at least one gross error: the synopsis is obsolete. slattach(8) refers to uustat(1), but uustat(1) doesn't exist. Chapter 21.7 of the handbook is absolutly useless in conjunction with 5.3-RELEASE.

Does these things have a background or a specific reason? Is there an easy alternative? Was SLIP declared as obsolete but someone forgot to document it?

Best regards
Björn
