The optional npackets entry is the number of packets to transmit. If you
specify npackets, then you must also specify a data_size.
The ping command display looks something like this:
To exit out of ping either wait for npackets to be transmitted or, at any
point, type q . The ping statistics display upon exit.
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 CSMIM-T1
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.
