Running the Echo Test
Run the Echo test to test the ability of the NIC to transmit
and receive data while it is connected to the network. To
run the Echo test, you need two PCs networked together.
In addition, the two PCs must each have a 3Com NIC
installed. Also make sure that the network driver is
installed. The first PC is used to send data; the second
PC receives the data sent from the first PC.
CAUTION: Running the Echo test while connected to
an active network can cause intermittent failures within
the test.
