Loopback
Test
.
This is a pass fail test and will take a second or two to complete. Repeat for
each port that needs testing.
The loopback test test the modem control (hardware handshaking) signals. It
only has meaning in RS-232 mode on serial connector interfaces with full RS-
232 signals. If performed under the following conditions, the test will always
fail because full modem control signals are not present:
•
RS-422
•
RS-485
•
RJ11 connectors
8.
Close
Test Terminal
If both of these tests successfully complete, then the port is operational as
expected.
Note:
Do NOT forget to restart the communications application.
