ETHERTX_CRS
Ethernet carrier
sense did not
assert in response
to transmission.
May be reported if
transmission is in
progress when
Ethernet is
disconnected.

86 5,6,3 TXQUIET
ETHERTX_LATECOLL
Late collision
occurred during
transmission.
Late collisions can
occur on a repeater
network if network
diameter exceeds
200 meters.
CobraNet's
collision avoidance
mechanism for
repeaters allows
network diameters
up to 2 kilometers.
On such networks,
late collisions are
expected in
transmission of
control data. The
collision detection
mechanism of a
device on the
network is
inoperative or a
device is
mistakenly
manually
configured for full-
duplex operation
on a repeater
network.

Received an
illegally short

Collisions are
occurring on the

A transmitter on
the network is
