Adaptec ANA-69000, ANA-62000 manual Command sequence is critical! The two commands

DuraLAN Fast Ethernet NICs User’s Guide

Command	Test
internal_100_mac	Test internal loop-back at 100 Mbps within the
	chip.
internal_10_phy	Tests loop-back from the physical device at
	10 Mbps.
internal_100_phy	Tests loop-back from the physical device at
	100 Mbps.
external_10	This test requires a loop-back cable. It tests the
	loop-back from the cable at 10 Mbps.
external_100	This test requires a loop-back cable. It tests the
	loop-back from the cable at 100 Mbps.
autonegotiate	Tests the speed the card negotiates. This test has
<speed>	five options:
(speed is one of five	0 — Tests for full autonegotiation (highest speed)
options)	10 — Forces test at 10 Mbps half duplex
	20 — Forces test at 10 Mbps full duplex
	100 — Forces test at 100 Mbps half duplex
	200 — Forces test at 100 Mbps full duplex
	Note: Requires a hub, switch, or loop-back cable.
	Also, autonegotiate defaults to 10MBytes if the
	cable is not connected.
checksum	Tests the abilitiy to calculate TCP/IP checksum.
statistics	Verifies statistics gathering features of the chip.
echoer #/sender #	This test requires two computers on a private
(where # is the	network: one as the sender, and the other as the
number of packets	echoer. This test is useful for testing the network
to send)	and verifying that data is being passed between
	the echoer and the sender.
	Enter the echoer command first, and then enter
	the sender command in the sender system. (This
	command sequence is critical!) The two commands
	work in tandem. The echoer system displays the
	number of packets received and then exits. The
	sender system displays a summary of packets
	transmitted and received, corrupted packets,
	number of collisions, and lost packets.
pause	Tests the flow controller features of the chip.
mem (default)	Slave access set to memory mode.
io	Slave access set to io mode.
