- Place the loopback plug into the corresponding port on the Digi product. This loopback plug is shipped with the product.
- From your UNIX root prompt type:
cat < /dev/[port_name] &
date > /dev/[port_name]
If you see the date display on the screen where you issued the commands, this would indicate that the port is functioning properly.
- Stop the initial cat command that is running in the background by typing:
kill 0
NOTE: The [port_name] will vary depending on the UNIX flavor. Please see your installation guide if you do not know the particular port naming convention for your system.
