Loopback Testing on Device/Terminal Servers Using Connect

1. Plug the RJ-45 loopback plug into the serial port to be tested.

2. From the UNIX root prompt, telnet to the IP address of the Digi device server.

An example is: telnet 143.191.2.151

3. From the PortServer prompt set the port to a printer device type. We will use port one in the examples:

set port dev=prn range=1)
kill tty=1

4. Enter connect 1 (one) to connect to the first serial port. The following message appears:

Set escape character to ^[

5. Start typing characters on your keyboard. The characters you type should display on your PC monitor (once). If you remove the loopback plug from the port and type data on the connect session, you should not see any data on your screen.

Repeat this test if you have other ports to test. To disconnect from the port, type: Ctrl-[ . (Control right square bracket, followed by a period), then press [Enter].
