NWSTAT(8) — Unix Programmer’s Manual
NAME
nwstat − report Ethernet Packet Transmission Firmware status
SYNOPSIS
nwstat [ -z [ dev ]] [ -g [ dev ]] [ -l file ] [ -r [ dev ]] [ -d [ file ] [ dev ]]
DESCRIPTION
Nwstat reports the Ethernet Packet Transmission Firmware status of an Integrated Solutions VME-ECX. A table of statistics is maintained by the Ethernet Packet Transmission Firmware in dual-ported RAM. This table may be read at any time. The statistics are reported on stdout. The program uses the device entry in /dev/nwr0 by default when dev is missing.
OPTIONS
NOTE: If no arguments are specified, statistics are automatically printed.
-z [ dev ] Zeros statistics.
-g [ dev ] Issues go command.
-l file [ dev ] Downloads file.
-r [ dev ] Resets board.
-d file [ dev ]
Dumps dual-ported memory.
FILES
/dev/nwrndual-ported RAM of VME Ethernet Card

BUGS
The table of statistics is not protected by a semaphore. That means occasionally the statistics will be read by nwstat while the firmware is updating them. That causes one of the statistics to be corrupted.
