Cyclades Technical Support is always ready to help with any configuration problems. Before calling,
execute the command
cat /proc/version
and note the Linux version and Cyclades-TS version written to the screen. This will speed resolution
of most problems.
Hardware Test
A hardware test called tstest is included with the Cyclades-TS firmware. It is a menu-driven program, run by
typing tstest at the command prompt, and the various options are described below. Note that the Cyclades-TS
should not be tested while in use as the test will inactivate all ports.
Port Test
Either a cross cable or a loop-back connector is necessary for this test. The pinout diagrams are supplied in
appendix B. Connect the loop-back connector to the modem cable and then connect the modem cable to the
port to be tested (or connect a cross cable between two ports to be tested). When tstest senses the presence
of the cable or connector, the test will be automatically run and the result shown on the screen.
Each line of data correponds to a port in test. The last 4 columns (DATA, CTS, DCD, and DSR) indicate errors.
The values in these columns should be zero. The figure below is an example of the output screen.
<- Packets -> <- Errors ->
From To Sent Received Passes Data CTS DCD DSR
2 <-> 2 35 35 35 0 0 0 0
4 <-> 5 35 35 35 0 0 0 0
5 <-> 4 35 35 35 0 0 0 0
When this test is run with a cable or connector without the DSR signal (see the pinout diagram for the cable or
connector being used), errors will appear in the DSR column. This does not indicate a problem with the port. In
the example above, tstest perceived that a loop-back connector was attached to port 2 and that a cross cable
