slattach is used to assign a tty line to a network
  interface which uses asynchronous serial lines.
Currently the slattach command is used to
    attach sl(4) interfaces. These
    interfaces have to be created using the
    ifconfig(8). The resulting
    point-to-point link is not a broadcast interface and normally has a netmask
    of 255.255.255.255. create subcommand before the
    slattach command. The network source and destination
    addresses and other interface parameters are configured via
    ifconfig(8).
The following operands are supported by
    slattach:
-H-h-l-m-n-s
    baudrate-t
    ldiscttyXX’, or
      ‘/dev/ttyXX’.Only the super-user may attach a network interface.
To detach the interface, use “ifconfig
    interface-name down” after killing off the
    slattach process.
    Interface-name is the name that is shown by
    netstat(1).

slattach command. There is no way to see which
  interface is assigned to the specified tty by the
  slattach command, either.
It would be better if the network interfaces were created by the
    slattach command rather than by using the
    ifconfig(8)
    create subcommand before the
    slattach command.
