+.SH NAME
+slstat \- report serial line IP statistics
+.SH SYNOPSIS
+.nf
+.ft B
+slstat  [ \-i interval ] [ \-v ] [ \-r ] [ unit ] [ system ] [ core ]
+.ft R
+.fi
+.SH DESCRIPTION
+.I Slstat
+reports certain kernel statistics kept about serial line internet
+protocol traffic.
+.PP
+The options are as follows:
+.TP
+\-i
+Repeat the display indefinitely every
+.I interval
+seconds.
+If no
+.I interval
+is specified, the default is 5 seconds.
+.TP
+\-v
+Verbose display of extra fields of information.
+.TP
+\-r
+Display all values in rate per second that ammount per interval.
+.TP
+unit
+is a single digit specifying the slip interface. The default unit is
+.I 0
+for interface
+.I sl0.
+.TP
+system
+Extract the name list from the specified system instead of the default, /386bsd.
+.TP
+core
+Extract values associated with the name list from the specified
+core instead of the default, /dev/kmem.
+.PP
+By default,
+.I vmstat
+displays the following information:
+.PP
+.TP
+in
+bytes received
+.TP
+out
+bytes sent
+.TP
+pack
+packets received or sent
+.TP
+comp
+compressed packets received or sent
+.TP
+uncomp
+uncompressed packets received or sent
+.TP
+unknwn
+inbound packets of unknown type
+.TP
+toss
+inbound packets tossed because of error
+.TP
+other
+all other inbound or outbound ip packets
+.TP
+err
+input or output errors
+.TP
+search
+searches for connection state
+.TP
+miss
+times we could not find a connectoin state
+.TP
+coll
+collisions with end of clists.
+If you get many collisions (more than one or two
+a day) you probably do not have enough clists
+and you should increase "nclist" in param.c.
+.SH EXAMPLES
+The command ``slstat -i 5'' will print what the system is doing every five
+seconds.
