> The LAN station monitor (Ethernet station monitor on versions prior to
1.3.0) discovers MAC addresses and displays statistics on the number
of incoming, and outgoing packets. It also includes figures for incoming
and outgoing kilobits per second for each discovered station.</P
><P
> The entry above each line of statistics is the station's LAN
type (Ethernet, PLIP, or FDDI) and the hardware MAC address.
Each statistics line consists of the following information:</P

by total outgoing packets, O to sort by outgoing IP packets, and Y to
sort by total outgoing bytes. Pressing any other key cancels the sort.</P
