references, add a little white space here & there for readability, clean up some mdoc(7) macro usage and so on. Whew!

.Sh NAME
|
|
.Nm sl
|
|
.Nd Serial Line IP (SLIP) network interface
|
|
.Sh SYNOPSIS
|
|
.Cd pseudo-device sl Op Ar count
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
interface allows asynchronous serial lines to be used as
|
|
.Tn IP
|
|
network interfaces using the
|
|
.Tn SLIP
|
|
protocol.
|
|
The
|
|
.Nm
|
|
interface can use Van Jacobson
|
|
.Tn TCP
|
|
header compression and
|
|
.Tn ICMP
|
|
filtering.
|
|
.Pp
|
|
However,
|
|
.Tn SLIP
|
|
can only transmit
|
|
.Tn IP
|
|
packets between preconfigured hosts on an asynchronous serial link.
|
|
It has no provision for address negotiation,
|
|
carriage of additional protocols (e.g.
|
|
.Tn XNS ,
|
|
.Tn AppleTalk ,
|
|
.Tn DECNET ) ,
|
|
and is not designed for synchronous serial links.
|
|
This is why
|
|
.Tn SLIP
|
|
has been superceded by the Point-to-Point Protocol
|
|
.Pq Tn PPP ,
|
|
which does all of those things, and much more.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It sl%d: af%d not supported.
|
|
The interface was handed
|
|
a message with addresses formatted in an unsuitable address
|
|
family; the packet was dropped.
