Start/Stop Target Communication
The Xenta 913 target communications can be started and stopped at any
time without restarting the whole gateway application. When the
Xenta 913 is first started, there is a ten second pause before the gateway
application starts up, allowing you to prevent it from running when con-
ducting a separate test.
The Xenta 913 is started and stopped using the following command for-
mat:
vx S s
where S selects the start/stop command, and s is the required Stop/Start
mode (0 for stop, 1 for Start). Simply typing vx s toggles the Xenta 913
communications on or off. The communications log activity is immedi-
ately printed on the HyperTerminal screen.
On the Xenta 913 web site, there is a web page for starting and stopping
the communication.
Enable/Disable Target Communication Log
Normally, the communications log activity is only shown on the termi-
nal screen, so older messages are lost. However, it is possible to enable
or disable logging to file by using the following command format.
vx L h
where L selects the log-to-file command, and h is the maximum number
of hours the log should be enabled (0 to 25).
Simply typing vx L toggles logging to file on or off.
Typing vx L 0 immediately turns off logging to file, whereas an h value
greater than 0 enables logging to file for up to the requested number of
hours.
Verbosity
The amount of information recorded by the diagnostics log is controlled
by the verbosity level. The default verbosity level of 1 shows only com-
munications error messages. A medium verbosity level of 6 or 7 gener-
ally shows I/O value activity, which can be very useful for finding
configuration errors.
