The
interface allows serial lines to be used as network interfaces using the
point-to-point
protocol.
The
interface can use various types of compression and has many features over
the
sl(4)
protocol.
Each
interface is created at runtime using interface cloning.
This is most easily done with the
ifconfig(8)
create
command or using the
cloned_interfaces
variable in
rc.conf5.
DIAGNOSTICS
