Running the Echo Test

The echo test tests the 3C905B-TX NIC's ability to transmit
and receive data while on the network.
You need two PCs with 3Com NICs installed to run an echo
test: one PC to send data and one PC to receive data.
CAUTION: Running the echo test while connected to an
active network can cause intermittent failures. To avoid
this, connect to an inactive network on which only the PC
being tested is operating.
To run the echo test, follow these steps:
1 Make sure that the 3C905B-TX NIC is installed in the
sending PC and connected to the network (Chapter 2)
and that the network driver is installed (Chapter 3).
2 Install a 3C905B-TX NIC in another PC (the echo server),
connect it to the network, and install the network
driver.
The echo server PC is the responding PC.

a Click the Windows Start menu.
b Select Programs.
