Echo Exchange Test
To test the PC CardOs ability to transmit and receive data
while on the network, run the echo exchange test.
CAUTION: Do not use an active network to run the echo
exchange test. The test packets transmitted and received by the
PC Card are nonstandard and may slow network response time.
To run the echo exchange test on the network, you need a
second PC set up as an echo server. The echo server receives
packets from the EtherLink III PC Card being tested and
echoes them back to the PC Card. The second PC must
contain a 3Com PC Card or adapter running EtherDisk
To set up an echo server, follow these steps:
1 Select a PC to use as an echo server.
