3.2.14 ports
The ports command tests serial line ports, exercising both the data lines
and the control lines for each serial port specified. The syntax for this
command is:
ports [–d]
Each serial port to be tested must be looped-back with a loopback plug to
test both the data lines and the control lines (the accessory kit provides a
loopback plug). Connect this plug to the connector on the Micro-CS that
corresponds to the port to be tested.
When invoked, the command displays a menu of options.
NOTE
Do not run the ports command for a port to which a device is
connected. The test will transmit data to the device and toggle
its control lines.
