     sl -- slip network interface

SYNOPSIS    [Toc]    [Back]

     device sl [count]

     The sl interface allows serial lines to be used as network interfaces
     using the slip protocol.  The sl interface can use Van Jacobson TCP
     header compression and ICMP filtering.  This is arranged by using the

     link1   Suppress ICMP traffic.
     link2   Enable VJ header compression autodetection.  This will turn on
